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
Notes:
*The INIT bit must not be set or the initialization block will be accessed instead.
**Needed only if SSIZE32 =0.
