Although the SPI Relay driver is RC2014-specific, the SD Card driver is generic enough to be a subsystem. That's the second subsystem we add and this warrants, I think, the formalization of a new concept: protocols.

SD Card subsystem
|
|
|
|
Load range: B423-B436
|
|
|
|
This subsystem is designed for a ad-hoc adapter card that acts
|
|
as a SPI relay between the z80 bus and the SD card. It requires
|
|
a driver providing the SPI Relay protocol.
|
|
|
|
Through that layer, this driver implements the SDC protocol
|
|
allowing it to provide BLK@ and BLK!.
