Alternative Method for
Initialization
APPENDIX D: Alternative Method for Initialization
The Am79C973/Am79C975 controller may be initial-
ized by performing I/O writes only. That is, data can be
written directly to the appropriate control and status
registers (CSR instead of reading from the initialization
block in memory). The registers that must be written
Note:
1. The INIT bit must not be set or the initialization block will be accessed instead.
2. Needed only if SSIZE32 =0.
3. Needed only if the physical address is different from the one stored in EEPROM or if there is no EEPROM present.
