Cache Extended Memory Area
If enabled, this feature allows the data stored in the extended memory area to
be cached (written) into a buffer, a storage area in the Static DROM (SDROM) or
written into L1, L2, L3 cache inside the CPU to speed up CPU operations. Select
Uncached to disable this function. Select Write Through to allow data to be cached
into the buffer and written into the system memory at the same time. Select Write
Protect to prevent data from being written into the extended memory area above 1
MB. Select Write Back to allow the CPU to write data back directly from the buffer
without writing data to the System Memory for fast CPU data processing and opera-
tion. The options are Uncached, Write Through, Write Protect, and Write Back.
