Cache Extended Memory
If enabled, this feature will allow the data stored in the extended memory
area to be cached (written) into a buffer, a storage area in the Static DRM
(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
operation. The options are Uncached, Write Through, Write Protect, and
Write Back.
