SPI relay driver
|
||
|
|
|
||
|
|
This driver is designed for a ad-hoc adapter card that acts as a
|
||
|
|
SPI relay between the z80 bus and the SPI device. Sending any-
|
||
|
|
thing on SPI_CSLOW and SPI_CSHIGH is expected to select/deselect
|
||
|
|
the device, and writing to SPI_DATA is expected to initiate a
|
||
|
|
byte exchange. The result of the exchange is excpected to be re-
|
||
|
|
trieved by reading SPI_DATA.
|
||
|
|
|
||
|
|
Provides (spie) (enable), (spid) (disable), (spix) (xchange).
|
||
|
|
|
||
|
|
Load driver with "596 LOAD".
