Timing Pack of BANK0/1/2
Timing Pack of
BANK0/1/2/3:
- Slow
- Medium
- Fast
- Fastest
The value in this field depends on performance
parameters of the installed memory chips (DRAM).
Do not change the value from the factory setting
unless you install new memory that has a different
performance rating than the original DRAMs.
Ø
SDRAM CAS Latency of BANK0/1/2
SDRAM CAS
Latency of
BANK0/1/2/3:
- 2 clocks
- 3 clocks
When synchronous DRAM is installed, the number of
clock cycles of CAS latency depends on the DRAM
timing. Do not reset this field from the default value
specified by the system designer.
Ø
Auto Configuration
Auto Configuration:
- Enabled
- Disabled
This item allows you select pre-determined optimal
values for DRAM, cache, and timing according to
CPU type & system clock.

Ø
AT Bus Clock
AT Bus Clock:
- 7.16MHz
- CLK2/2
- CLK2/3
- CLK2/4
- CLK2/5
- CLK2/6
You can set the speed of the AT bus in terms of a
fraction of the CPU clock speed (PCLK2), or at the
fixed speed of 7.16 MHz.
