Alternative Method for
Initialization
The controller may be initialized 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 A-1.
Notes:
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.
