APPENDIX C
Am79C971
C-1
Alternative Method for Initialization*
The Am79C971 controller may be initialized by per-
forming I/O writes only. That is, data can be written di-
rectly 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 the table below. These register writes are followed by
writing the START bit in CSR0.
Notes:
*The INIT bit must not be set or the initialization block will be accessed instead.
**Needed only if SSIZE32 =0.
