, for appropriate values. The
default value varies according to the system’s bus clock speed.
Note
ROM First Access Length is not applicable to the MCP750. The
configured value is ignored by PPCBug.
ROM Next Access Length (0 - 15) = 0?
The value programmed into the MPC105 ROMNAL field (Memory
Control Configuration Register 8: bits 28-31) to represent wait states
in access time for nibble (or burst) mode ROM accesses. The lowest
allowable ROMNAL setting is $0; the highest allowable is $F. The
value to enter depends on processor speed; refer to your
Processor/Memory Mezzanine Module User’s Manual for appropriate
values. The default value varies according to the system’s bus clock
speed.
Note
ROM Next Access Length is not applicable to the MCP750HA.
The configured value is ignored by PPCBug.
DRAM Parity Enable [On-Detection/Always/Never - O/A/N] = 0?
Note
This parameter (above) also applies to enabling ECC for DRAM.
L2 Cache Parity Enable [On-Detection/Always/Never - O/A/N] = O?
O
DRAM parity is enabled upon detection. (Default)
A
DRAM parity is always enabled.
N
DRAM parity is never enabled
O
L2 Cache parity is enabled upon detection. (Default)
