.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for driving an IEEE-488 bus, also called
|
|
IEC-625 (or just "IEC bus"), or HP-IB (Hewlett Packard Instrument
|
|
Bus), or GPIB (General Purpose Instrument Bus).
|
|
The driver supports National Instruments PCIIA cards (sometimes
|
|
also refered to as PC2A) and compatibles.
|
|
These cards use a NEC \(mcPD7210 controller IC as the main
|
|
interface between the host computer and the instrument bus.
|
|
.Ss IO memory space layout
|
|
The PCIIA cards use a very specific IO memory space allocation layout.
|
|
The address bits A0 through A9 (which have traditionally been the only
|
|
address bits evaluated on IBM PC XT extension cards) are hardwired to
|
|
address 0x2e1.
|
|
Bits A10 through A12 are used by the \(mcPD7210 register select lines.
|
|
This makes the individual 7210 registers being 0x400 bytes apart in the
|
|
ISA bus address space.
|
|
Address bits A13 and A14 are compared to a DIP switch setting on the
|
|
card, allowing for up to 4 different cards being installed (at base
|
|
addresses 0x2e1, 0x22e1, 0x42e1, and 0x62e1, respectively).
|
|
A15 has been used to select an optional on-board time-of-day clock
|
|
chip (MM58167A) on the original PCIIA rather than the \(mcPD7210
|
|
(which is not implemented on later boards and clones).
|
|
Finally, the IO addresses 0x2f0 ... 0x2f7 are used for a
|
|
.Em special interrupt handling feature
|
|
(re-enable interrupts so the IRQ can be shared), where actually only
|
|
address 0x2f0 plus the actual IRQ level is required for each card.
|
|
Some clones do not appear to require this special IRQ handling, and
|
|
are thus likely to not support the shared IRQ feature.
|
|
.Pp
|
|
Only the base address of the card needs to be specified in the ISA
|
|
device hints; the driver takes care to derive all other IO addresses
|
|
needed during the probe phase.
|
