Raw Blame History 

  1. SD Card subsystem

  2. 

  3. Load range: B423-B436

  4. 

  5. This subsystem is designed for a ad-hoc adapter card that acts

  6. as a SPI relay between the z80 bus and the SD card. It requires

  7. a driver providing the SPI Relay protocol. You need to define

  8. SDC_DEVID to specify which ID will be supplied to (spie).

  9. 

  10. Through that layer, this driver implements the SDC protocol

  11. allowing it to provide BLK@ and BLK!.
