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

are shown in Table D-76. These register writes are fol-

lowed by writing the START bit in CSR0.

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.
