|
*
|
|
* the card uses 2 i/o addressranges each using 2 bytes
|
|
*
|
|
* addressrange 0:
|
|
* offset 0 - ISAC dataregister
|
|
* offset 1 - HSCX dataregister
|
|
* addressrange 1:
|
|
* offset 0 - ISAC addressregister
|
|
* offset 1 - HSCX addressregister
|
|
*
|
|
* to access an ISAC/HSCX register, you have to write the register
|
|
* number into the ISAC or HSCX addressregister and then read/write
|
|
* data for the ISAC/HSCX register into/from the corresponding
|
|
* dataregister.
