WAFER-L

1.1.7 CPU Feature

The CPU Feature menu (BIOS Menu 5) shows CPU configuration options.

BIOS Menu 5: CPU Feature

 CPU Frequency [500 MHz]

This option allows you to change the CPU FSB frequency. Setting this value too high may

damage your embedded board.

 Memory Frequency [333 MHz]

This option allows you to manually change the operating frequency of your system memory.

Setting this value too high may damage your embedded board.

 CAS Latency [Auto]

This controls the time delay (in clock cycles - CLKs) that passes before the SDRAM starts to carry

out a read command after receiving it. This also determines the number of CLKs for the

completion of the first part of a burst transfer. In other words, the lower the latency, the faster the

transaction. Note that some SDRAM modules may not be able to handle the lower latency and

will become unstable and lose data.
