* * SRXDLCK
|
|
|
|
|
* When asserted, this bit locks the Spi4 receive DLLs. This bit also
|
|
|
|
|
* acts as the Spi4 receiver reset and must be asserted before the
|
|
|
|
|
* training sequences are used to initialize the interface. This bit
|
|
|
|
|
* only applies to the receiver interface.
|
|
|
|
|
*
|
|
|
|
|
* * RCVTRN
|
|
|
|
|
* Once the SRXDLCK bit is asserted and the DLLs have locked and the
|
|
|
|
|
* system has been programmed, software should assert this bit in order
|
|
|
|
|
* to start looking for valid training sequence and synchronize the
|
|
|
|
|
* interface. This bit only applies to the receiver interface.
|
|
|
|
|
*
|
|
|
|
|
* * DRPTRN
|
|
|
|
|
* The Spi4 receiver can either convert training packets into NOPs or
|
|
|
|
|
* drop them entirely. Dropping ticks allows the interface to deskew
|
|
|
|
|
* periodically if the dclk and eclk ratios are close. This bit only
|
|
|
|
|
* applies to the receiver interface.
|
|
|
|
|
*
|
|
|
|
|
* * SNDTRN
|
|
|
|
|
* When software sets this bit, it indicates that the Spi4 transmit
|
|
|
|
|
* interface has been setup and has seen the calendare status. Once the
|
|
|
|
|
* transmitter begins sending training data, the receiving device is free
|
|
|
|
|
* to start traversing the calendar table to synch the link.
|
|
|
|
|
*
|
|
|
|
|
* * STATRCV
|
|
|
|
|
* This bit determines which status clock edge to sample the status
|
|
|
|
|
* channel in Spi4 mode. Since the status channel is in the opposite
|
|
|
|
|
* direction to the datapath, the STATRCV actually effects the
|
|
|
|
|
* transmitter/TX block.
|
|
|
|
|
*
|
|
|
|
|
* * STATDRV
|
|
|
|
|
* This bit determines which status clock edge to drive the status
|
|
|
|
|
* channel in Spi4 mode. Since the status channel is in the opposite
|
|
|
|
|
* direction to the datapath, the STATDRV actually effects the
|
|
|
|
|
* receiver/RX block.
|
|
|
|
|
*
|
|
|
|
|
* * RUNBIST
|
|
|
|
|
* RUNBIST will beginning BIST/BISR in all the SPX compilied memories.
|
|
|
|
|
* These memories are...
|
|
|
|
|
*
|
|
|
|
|
* * spx.srx.spi4.dat.dpr // FIFO Spi4 to IMX
|
|
|
|
|
* * spx.stx.cal.calendar // Spi4 TX calendar table
|
|
|
|
|
* * spx.srx.spi4.cal.calendar // Spi4 RX calendar table
|
|
|
|
|
*
|
|
|
|
|
* RUNBIST must never be asserted when the interface is enabled.
|
|
|
|
|
* Furthmore, setting RUNBIST at any other time is destructive and can
|
|
|
|
|
* cause data and configuration corruption. The entire interface must be
|
|
|
|
|
* reconfigured when this bit is set.
|
|
|
|
|
*
|
|
|
|
|
* * CLKDLY
|
|
|
|
|
* CLKDLY should be kept at its reset value during normal operation. This
|
|
|
|
|
* register controls the SPI4.2 static clock positioning which normally only is
|
|
|
|
|
* set to the non-reset value in quarter clocking schemes. In this mode, the
|
|
|
|
|
* delay window is not large enough for slow clock freq, therefore clock and
|
|
|
|
|
* data must be statically positioned with CSRs. By changing the clock position
|
|
|
|
|
* relative to the data bits, we give the system a wider window.
|
|
|
|
|
*
|
|
|
|
|
* * SEETRN
|
|
|
|
|
* In systems in which no training data is sent to N2 or N2 cannot
|
|
|
|
|
* correctly sample the training data, software may pulse this bit by
|
|
|
|
|
* writing a '1' followed by a '0' in order to correctly set the
|
|
|
|
|
* receivers state. The receive data bus should be idle at this time
|
|
|
|
|
* (only NOPs on the bus). If N2 cannot see at least on training
|
|
|
|
|
* sequence, the data bus will not send any data to the core. The
|
|
|
|
|
* interface will hang.

|
|
|
* and make any adjustments by hand. These steps should only be taken
|
|
|
|
|
* once the RCVTRN bit is set and before any real traffic is sent on the

|
|
* improper programmings can cause catestrophic or intermitent problems.
|
|

|
|
|
|
|
* tap selects.
|
|
|
|
|
*
|
|
|

|
|
|
|
* For the xcv delay taps, the CSR controls increment and decrement the
|
|
|
|
|
* 5-bit count value in the XCV. This is a saturating counter, so it
|
|
|
|
|
* will not wrap when decrementing below zero or incrementing above 31.
|
|
|
|
|
*
|
|
|
|
|
* To write...
|
|
|
|
|

|
|
|
|
|
* SPXX_DBG_DESKEW_CTL[BITSEL] = bit to set
|
|
|

|
|
|
|
|
* SPXX_DBG_DESKEW_CTL[INC|DEC] = go bit
|
|
|
|
|
*
|
|
|
|
|
* These values are copied in SPX, so that they can be read back by

|
* SPXX_DBG_DESKEW_STATE[OFFSET] = 5-bit value
|
|
|
|
|
*
|
|
|
|
|
* In addition, there is a reset bit that sets all the state back to the
|
|
|
|
|
* default/starting value of 0x10.
|
|
|
|
|

|
|

|
|
|
|
|
*
|
|
|
|
|
* SINGLE STEP TRAINING MODE (WILMA)
|
|
|
|
|
* Debug feature that will enable the user to single-step the debug
|
|
|
|
|
* logic to watch initial movement and trends by putting the training
|
|
|
|
|
* machine in single step mode.
|
|
|
|
|
*
|
|
|
|
|
* * SPX*_DBG_DESKEW_CTL[SSTEP]
|
|
|
|
|
* This will put the training control logic into single step mode. We
|
|
|
|
|
* will not deskew in this scenario and will require the TX device to
|
|
|
|
|
* send continuous training sequences.
|
|
|
|
|
*
|
|
|
|
|
* It is required that SRX*_COM_CTL[INF_EN] be clear so that suspect
|
|
|
|
|
* data does not flow into the chip.
|
|
|
|
|
*
|
|
|
|
|
* Deasserting SPX*_DBG_DESKEW_CTL[SSTEP] will attempt to deskew as per
|
|
|
|
|
* the normal definition. Single step mode is for debug only. Special
|
|
|
|
|
* care must be given to correctly deskew the interface if normal
|
|
|
|
|
* operation is desired.
|
|
|
|
|
*
|
|
|
|
|
* * SPX*_DBG_DESKEW_CTL[SSTEP_GO]
|
|
|
|
|
* Each write of '1' to SSTEP_GO will go through a single training
|
|
|
|
|
* iteration and will perform...
|
|
|
|
|
*
|
|
|
|
|
* - DLL update, if SPX*_DBG_DESKEW_CTL[DLLDIS] is clear
|
|
|
|
|
* - coarse update, if SPX*_TRN4_CTL[MUX_EN] is set
|
|
|
|
|
* - single fine update, if SPX*_TRN4_CTL[MACRO_EN] is set and an edge
|
|
|
|
|
* was detected after walked +/- SPX*_TRN4_CTL[MAXDIST] taps.
|
|
|
|
|
*
|
|
|
|
|
* Writes to this register have no effect if the interface is not in
|
|
|
|
|
* SSTEP mode (SPX*_DBG_DESKEW_CTL[SSTEP]).
|
|
|
|
|
*
|
|
|
|
|
* The WILMA mode will be cleared at the final state transition, so
|
|
|
|
|
* that software can set SPX*_DBG_DESKEW_CTL[SSTEP] and
|
|
|
|
|
* SPX*_DBG_DESKEW_CTL[SSTEP_GO] before setting SPX*_CLK_CTL[RCVTRN]
|
|
|
|
|
* and the machine will go through the initial iteration and stop -
|
|
|
|
|
* waiting for another SPX*_DBG_DESKEW_CTL[SSTEP_GO] or an interface
|
|
|
|
|
* enable.
|
|
|
|
|
*
|
|
|
|
|
* * SPX*_DBG_DESKEW_CTL[FALL8]
|
|
|
|
|
* Determines how many pattern matches are required during training
|
|
|
|
|
* operations to fallout of training and begin processing the normal data
|
|
|
|
|
* stream. The default value is 10 pattern matches. The pattern that is
|
|
|
|
|
* used is dependent on the SPX*_DBG_DESKEW_CTL[FALLNOP] CSR which
|
|
|
|
|
* determines between non-training packets (the default) and NOPs.
|
|
|
|
|
*
|
|
|
|
|
* * SPX*_DBG_DESKEW_CTL[FALLNOP]
|
|
|
|
|
* Determines the pattern that is required during training operations to
|
|
|
|
|
* fallout of training and begin processing the normal data stream. The
|
|
|
|
|
* default value is to match against non-training data. Setting this
|
|
|
|
|
* bit, changes the behavior to watch for NOPs packet instead.
|
|
|
|
|
*
|
|
|
|
|
* This bit should not be changed dynamically while the link is
|
|
|
|
|
* operational.

|
|
* Notes:
|
|
|
|
|
* * PRTNXA
|
|
|
|
|
* This error indicates that the port on the Spi bus was not a valid port
|
|
|
|
|
* for the system. Spi4 accesses occur on payload control bit-times. The
|
|
|
|
|
* SRX can be configured with the exact number of ports available (by
|
|
|
|
|
* SRX_COM_CTL[PRTS] register). Any Spi access to anthing outside the range
|
|
|
|
|
* of 0 .. (SRX_COM_CTL[PRTS] - 1) is considered an error. The offending
|
|
|
|
|
* port is logged in SPX_INT_DAT[PRT] if there are no pending interrupts in
|
|
|
|
|
* SPX_INT_REG that require SPX_INT_DAT[PRT].
|
|
|
|
|
*
|
|
|
|
|
* SRX will not drop the packet with the bogus port address. Instead, the
|
|
|
|
|
* port will be mapped into the supported port range. The remapped address
|
|
|
|
|
* in simply...
|
|
|
|
|
*
|
|
|
|
|
* Address = [ interfaceId, ADR[3:0] ]
|
|
|
|
|
*
|
|
|
|
|
* If the SPX detects that a PRTNXA error has occured, the packet will
|
|
|
|
|
* have its ERR bit set (or'ed in with the ERR bit from the transmitter)
|
|
|
|
|
* if the SPX_ERR_CTL[PRTNXA] bit is clear.
|
|
|
|
|
*
|
|
|
|
|
* In Spi4 mode, SPX will generate an interrupt for every 8B data burst
|
|
|
|
|
* associated with the invalid address. The SPX_INT_DAT[MUL] bit will never
|
|
|
|
|
* be set.
|
|
|
|
|
*
|
|
|
|
|
* * ABNORM
|
|
|
|
|
* This bit simply indicates that a given packet had abnormal terminiation.
|
|
|
|
|
* In Spi4 mode, this means that packet completed with an EOPS[1:0] code of
|
|
|
|
|
* 2'b01. This error can also be thought of as the application specific
|
|
|
|
|
* error (as mentioned in the Spi4 spec). The offending port is logged in
|
|
|
|
|
* SPX_INT_DAT[PRT] if there are no pending interrupts in SPX_INT_REG that
|
|
|
|
|
* require SPX_INT_DAT[PRT].
|
|
|
|
|
*
|
|
|
|
|
* The ABNORM error is only raised when the ERR bit that comes from the
|
|
|
|
|
* Spi interface is set. It will never assert if any internal condition
|
|
|
|
|
* causes the ERR bit to assert (e.g. PRTNXA or DPERR).
|
|
|
|
|
*
|
|
|
|
|
* * SPIOVR
|
|
|
|
|
* This error indicates that the FIFOs that manage the async crossing from
|
|
|
|
|
* the Spi clocks to the core clock domains have overflowed. This is a
|
|
|
|
|
* fatal error and can cause much data/control corruption since ticks will
|
|
|
|
|
* be dropped and reordered. This is purely a function of clock ratios and
|
|
|
|
|
* correct system ratios should make this an impossible condition.
|
|
|
|
|
*
|
|
|
|
|
* * CLSERR
|
|
|
|
|
* This is a Spi4 error that indicates that a given data transfer burst
|
|
|
|
|
* that did not terminate with an EOP, did not end with the 16B alignment
|
|
|
|
|
* as per the Spi4 spec. The offending port cannot be logged since the
|
|
|
|
|
* block does not know the streamm terminated until the port switches.
|
|
|
|
|
* At that time, that packet has already been pushed down the pipe.
|
|
|
|
|
*
|
|
|
|
|
* The CLSERR bit does not actually check the Spi4 burst - just how data
|
|
|
|
|
* is accumulated for the downstream logic. Bursts that are separted by
|
|
|
|
|
* idles or training will still be merged into accumulated transfers and
|
|
|
|
|
* will not fire the CLSERR condition. The checker is really checking
|
|
|
|
|
* non-8B aligned, non-EOP data ticks that are sent downstream. These
|
|
|
|
|
* ticks are what will really mess up the core.
|
|
|
|
|
*
|
|
|
|
|
* This is an expensive fix, so we'll probably let it ride. We never
|
|
|
|
|
* claim to check Spi4 protocol anyway.
|
|
|
|
|
*
|
|
|
|
|
* * DRWNNG
|
|
|
|
|
* This error indicates that the Spi4 FIFO that services the GMX has
|
|
|
|
|
* overflowed. Like the SPIOVR error condition, correct system ratios
|
|
|
|
|
* should make this an impossible condition.
|
|
|
|
|
*
|
|
|
|
|
* * RSVERR
|
|
|
|
|
* This Spi4 error indicates that the Spi4 receiver has seen a reserve
|
|
|
|
|
* control packet. A reserve control packet is an invalid combiniation
|
|
|
|
|
* of bits on DAT[15:12]. Basically this is DAT[15] == 1'b0 and DAT[12]
|
|
|
|
|
* == 1'b1 (an SOP without a payload command). The RSVERR indicates an
|
|
|
|
|
* error has occured and SPX_INT_DAT[RSVOP] holds the first reserved
|
|
|
|
|
* opcode and will be set if there are no pending interrupts in
|
|
|
|
|
* SPX_INT_REG that require SPX_INT_DAT[RSVOP].
|
|
|
|
|
*
|
|
|
|
|
* * TPAOVR
|
|
|
|
|
* This bit indicates that the TPA Watcher has flagged an event. See the
|
|
|
|
|
* TPA Watcher for a more detailed discussion.
|
|
|
|
|
*
|
|
|
|
|
* * DIPERR
|
|
|
|
|
* This bit indicates that the Spi4 receiver has encountered a DIP4
|
|
|
|
|
* miscompare on the datapath. A DIPERR can occur in an IDLE or a
|
|
|
|
|
* control word that frames a data burst. If the DIPERR occurs on a
|
|
|
|
|
* framing word there are three cases.
|
|
|
|
|
*
|
|
|
|
|
* 1) DIPERR occurs at the end of a data burst. The previous packet is
|
|
|
|
|
* marked with the ERR bit to be processed later if
|
|
|
|
|
* SPX_ERR_CTL[DIPCLS] is clear.
|
|
|
|
|
* 2) DIPERR occurs on a payload word. The subsequent packet is marked
|
|
|
|
|
* with the ERR bit to be processed later if SPX_ERR_CTL[DIPPAY] is
|
|
|
|
|
* clear.
|
|
|
|
|
* 3) DIPERR occurs on a control word that closes on packet and is a
|
|
|
|
|
* payload for another packet. In this case, both packets will have
|
|
|
|
|
* their ERR bit marked depending on the respective values of
|
|
|
|
|
* SPX_ERR_CTL[DIPCLS] and SPX_ERR_CTL[DIPPAY] as discussed above.
|
|
|
|
|
*
|
|
|
|
|
* * SYNCERR
|
|
|
|
|
* This bit indicates that the Spi4 receiver has encountered
|
|
|
|
|
* SPX_ERR_CTL[ERRCNT] consecutive Spi4 DIP4 errors and the interface
|
|
|
|
|
* should be synched.
|
|
|
|
|
*
|
|
|
|
|
* * CALERR
|
|
|
|
|
* This bit indicates that the Spi4 calendar table encountered a parity
|
|
|
|
|
* error. This error bit is associated with the calendar table on the RX
|
|
|
|
|
* interface - the interface that receives the Spi databus. Parity errors
|
|
|
|
|
* can occur during normal operation when the calendar table is constantly
|
|
|
|
|
* being read for the port information, or during initialization time, when
|
|
|
|
|
* the user has access. Since the calendar table is split into two banks,
|
|
|
|
|
* SPX_INT_DAT[CALBNK] indicates which banks have taken a parity error.
|
|
|
|
|
* CALBNK[1] indicates the error occured in the upper bank, while CALBNK[0]
|
|
|
|
|
* indicates that the error occured in the lower bank. SPX_INT_DAT[CALBNK]
|
|
|
|
|
* will be set if there are no pending interrupts in SPX_INT_REG that
|
|
|
|
|
* require SPX_INT_DAT[CALBNK].
|
|
|
|
|
*
|
|
|
|
|
* * SPF
|
|
|
|
|
* This bit indicates that a Spi fatal error has occurred. A fatal error
|
|
|
|
|
* is defined as any error condition for which the corresponding
|
|
|
|
|
* SPX_INT_SYNC bit is set. Therefore, conservative systems can halt the
|
|
|
|
|
* interface on any error condition although this is not strictly
|
|
|
|
|
* necessary. Some error are much more fatal in nature than others.
|
|
|
|
|
*
|
|
|
|
|
* PRTNXA, SPIOVR, CLSERR, DRWNNG, DIPERR, CALERR, and SYNCERR are examples
|
|
|
|
|
* of fatal error for different reasons - usually because multiple port
|
|
|
|
|
* streams could be effected. ABNORM, RSVERR, and TPAOVR are conditions
|
|
|
|
|
* that are contained to a single packet which allows the interface to drop
|
|
|
|
|
* a single packet and remain up and stable.

* The TPA Watcher is primarily a debug vehicle used to help initial bringup
|
|

|
* of a system. The TPA watcher counts bytes that roll in from the Spi
|
|
|
|
|
* interface. The user programs the Spi port to watch using
|
|
|
|
|
* SPX_TPA_SEL[PRTSEL]. Once the TPA is deasserted for that port, the watcher
|
|
|
|
|
* begins to count the data ticks that have been delivered to the inbound
|
|
|
|
|
* datapath (and eventually to the IOB). The result is that we can derive
|
|
|
|
|
* turn-around times of the other device by watching how much data was sent
|
|
|
|
|
* after a loss of TPA through the SPX_TPA_ACC[CNT] register. An optional
|
|
|
|
|
* interrupt may be raised as well. See SPX_TPA_MAX for further information.
|
|
|
|
|
*
|
|
|
|
|
* TPA's can be deasserted for a number of reasons...
|
|
|
|
|
*
|
|
|
|
|
* 1) IPD indicates backpressure
|
|
|
|
|
* 2) The GMX inbound FIFO is filling up and should BP
|
|
|
|
|
* 3) User has out an override on the TPA wires

* * BOOT_BIT
|
|
|
|
|
* On the initial training synchronization sequence, the hardware has the
|
|
|
|
|
* BOOT_BIT set which means that it will continueously perform macro
|
|
|
|
|
* operations. Once the BOOT_BIT is cleared, the macro machine will finish
|
|
|
|
|
* the macro operation is working on and then return to the idle state.
|
|
|
|
|
* Subsequent training sequences will only go through a single macro
|

|
|
|
* operation in order to do slight deskews.
|
|
|
|
|
*
|
|
|
|
|
* * JITTER
|
|
|
|
|
* Minimum value is 1. This parameter must be set for Spi4 mode using

* auto-bit deskew. Regardless of the original intent, this field must be
|
|
|
|
|
* set non-zero for deskew to function correctly.
|
|
|
|
|
*
|
|
|
|
|
* The thought is the JITTER range is no longer required since the macro
|
|
|
|
|
* machine was enhanced to understand about edge direction. Originally

|
|
|
|
|
*
|
|

|
|
* * TRNTEST
|
|
|
|
|
* This mode is used to test systems to make sure that the bit deskew
|
|
|
|
|
* parameters have been correctly setup. After configuration, software can
|
|
|
|
|
* set the TRNTEST mode bit. This should be done before SRX_COM_CTL[ST_EN]
|
|
|
|
|
* is set such that we can be sure that the TX device is simply sending
|
|
|
|
|
* continuous training patterns.
|
|
|
|
|
*
|
|
|
|
|
* The test mode samples every incoming bit-time and makes sure that it is
|
|
|
|
|
* either a training control or a training data packet. If any other data
|
|
|
|

* is observed, then SPX_DBG_DESKEW_STATE[TESTRES] will assert signaling a

* test failure.
|
|
|
|
|
*
|
|
|
|
|
* Software must clear TRNTEST before training is terminated.
|
|
|
|
|
*
|
|
|
|
|
* * Example Spi4 RX init flow...
|
|
|
|
|
*
|
|
|
|
|
* 1) set the CLKDLY lines (SPXX_CLK_CTL[CLKDLY])
|
|
|
|
|
* - these bits must be set before the DLL can successfully lock
|
|
|
|
|
*
|
|
|
|
|
* 2) set the SRXDLCK (SPXX_CLK_CTL[SRXDLCK])
|
|
|
|
|
* - this is the DLL lock bit which also acts as a block reset
|
|
|
|
|
*
|
|
|
|
|
* 3) wait for the DLLs lock
|
|
|
|
|
*
|
|
|
|
|
* 4) set any desired fields in SPXX_DBG_DESKEW_CTL
|
|
|
|
|
* - This register has only one field that most users will care about.
|
|
|
|
|
* When set, DLLDIS will disable sending update pulses to the Spi4 RX
|
|
|
|
|
* DLLs. This pulse allows the DLL to adjust to clock variations over
|
|
|
|
|
* time. In general, it is desired behavior.
|
|
|
|
|
*
|
|
|
|
|
* 5) set fields in SPXX_TRN4_CTL
|
|
|
|
|
* - These fields deal with the MUX training sequence
|
|
|
|
|
* * MUX_EN
|
|
|
|
|
* This is the enable bit for the mux select. The MUX select will
|
|
|
|
|
* run in the training sequence between the DLL and the Macro
|
|
|
|
|
* sequence when enabled. Once the MUX selects are selected, the
|
|
|
|
|
* entire macro sequence must be rerun. The expectation is that
|
|
|
|
|
* this is only run at boot time and this is bit cleared at/around
|
|
|
|
|
* step \#8.
|
|
|
|
|
* - These fields deal with the Macro training sequence
|
|
|
|
|
* * MACRO_EN
|
|
|
|
|
* This is the enable bit for the macro sequence. Macro sequences
|
|
|
|
|
* will run after the DLL and MUX training sequences. Each macro
|
|
|
|
|
* sequence can move the offset by one value.
|
|
|
|
|
* * MAXDIST
|
|
|
|
|
* This is how far we will search for an edge. Example...
|
|
|
|
|
*
|
|
|
|
|
* dly: this is the intrinsic delay of each delay element
|
|
|
|
|
* tap currently, it is 70ps-110ps.
|
|
|
|
|
* U: bit time period in time units.
|
|
|
|
|
*
|
|
|
|
|
* MAXDIST = MIN(16, ((bit_time / 2) / dly)
|
|
|
|
|
*
|
|
|
|
|
* Each MAXDIST iteration consists of an edge detect in the early
|
|
|
|
|
* and late (+/-) directions in an attempt to center the data. This
|
|
|
|
|
* requires two training transistions, the control/data and
|
|
|
|
|
* data/control transistions which comprise a training sequence.
|
|
|
|
|
* Therefore, the number of training sequences required for a single
|
|
|
|
|
* macro operation is simply MAXDIST.
|
|
|
|
|
*

* 6) set the RCVTRN go bit (SPXX_CLK_CTL[RCVTRN])
|
|
|
|
|
* - this bit synchs on the first valid complete training cycle and
|
|
|
|
|
* starts to process the training packets
|
|
|
|
|
*
|
|
|
|
|
* 6b) This is where software could manually set the controls as opposed to
|
|
|
|
|
* letting the hardware do it. See the SPXX_DBG_DESKEW_CTL register
|
|
|
|
|
* description for more detail.
|
|
|
|
|
*
|
|
|
|
|
* 7) the TX device must continue to send training packets for the initial
|
|
|
|
|
* time period.
|
|
|
|
|
* - this can be determined by...
|
|
|
|
|
*
|
|
|
|
|
* DLL: one training sequence for the DLL adjustment (regardless of enable/disable)
|
|
|
|
|
* MUX: one training sequence for the Flop MUX taps (regardless of enable/disable)
|
|
|
|
|
* INIT_SEQUENCES: max number of taps that we must move
|
|
|
|
|
*
|
|
|
|
|
* INIT_SEQUENCES = MIN(16, ((bit_time / 2) / dly))
|
|
|
|
|
*
|
|
|
|
|
* INIT_TRN = DLL + MUX + ROUNDUP((INIT_SEQUENCES * (MAXDIST + 2)))
|
|
|
|
|
*
|
|
|
|
|
*
|
|
|
|
|
* - software can either wait a fixed amount of time based on the clock
|
|
|
|
|
* frequencies or poll the SPXX_CLK_STAT[SRXTRN] register. Each
|
|
|
|
|
* assertion of SRXTRN means that at least one training sequence has
|
|
|
|
|
* been received. Software can poll, clear, and repeat on this bit to
|
|
|
|
|
* eventually count all required transistions.
|
|
|
|
|
*
|
|
|
|
|
* int cnt = 0;
|
|
|
|
|
* while (cnt < INIT_TRN) [
|
|
|
|
|
* if (SPXX_CLK_STAT[SRXTRN]) [
|
|
|
|
|
* cnt++;
|
|
|
|
|
* SPXX_CLK_STAT[SRXTRN] = 0;
|
|
|
|
|
* ]
|
|
|
|
|
* ]
|
|
|
|
|
*
|
|
|
|
|
* - subsequent training sequences will normally move the taps only
|
|
|
|
|
* one position, so the ALPHA equation becomes...
|
|
|
|
|
*
|
|
|
|
|
* MAC = (MAXDIST == 0) ? 1 : ROUNDUP((1 * (MAXDIST + 2))) + 1
|
|
|
|
|
*
|
|
|
|
|
* ALPHA = DLL + MUX + MAC
|
|
|
|
|
*
|
|
|
|
|
* ergo, MAXDIST simplifies to...
|
|
|
|
|
*
|
|
|
|
|
* ALPHA = (MAXDIST == 0) ? 3 : MAXDIST + 5
|
|
|
|
|
*
|
|
|
|
|
* DLL and MUX and MAC will always require at least a training sequence
|
|
|
|
|
* each - even if disabled. If the macro sequence is enabled, an
|
|
|
|
|
* additional training sequenece at the end is necessary. The extra
|
|
|
|
|
* sequence allows for all training state to be cleared before resuming
|
|
|
|
|
* normal operation.
|
|
|
|
|
*
|
|
|
|
|
* 8) after the recevier gets enough training sequences in order to achieve
|
|
|
|
|
* deskew lock, set SPXX_TRN4_CTL[CLR_BOOT]
|
|
|
|
|
* - this disables the continuous macro sequences and puts into into one
|
|
|
|
|
* macro sequnence per training operation
|
|
|
|
|
* - optionally, the machine can choose to fall out of training if
|
|
|
|
|
* enough NOPs follow the training operation (require at least 32 NOPs
|
|
|
|
|
* to follow the training sequence).
|
|
|
|
|
*
|
|
|
|
|
* There must be at least MAXDIST + 3 training sequences after the
|
|
|
|
|
* SPXX_TRN4_CTL[CLR_BOOT] is set or sufficient NOPs from the TX device.
|
|
|
|
|
*
|
|
|
|
|
* 9) the TX device continues to send training sequences until the RX
|
|
|
|
|
* device sends a calendar transistion. This is controlled by
|
|
|
|
|
* SRXX_COM_CTL[ST_EN]. Other restrictions require other Spi parameters
|
|
|
|
|
* (e.g. the calendar table) to be setup before this bit can be enabled.
|
|
|
|
|
* Once the entire interface is properly programmed, software writes
|
|
|
|
|
* SRXX_COM_CTL[INF_EN]. At this point, the Spi4 packets will begin to
|
|
|
|
|
* be sent into the N2K core and processed by the chip.
