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. When writing
|
|
to SPI_CTL, we expect a bitmask of the device to select, with
|
|
0 meaning that everything is de-selected. Reading SPI_CTL
|
|
returns 0 if the device is ready or 1 if it's still running an
|
|
exchange. Writing to SPI_DATA initiates an exchange.
|
|
|
|
Provides the SPI relay protocol. Load driver with "596 LOAD".
