Cache Extended Memory Area
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 DROM (SDROM) or written
into the L1, L2, L3 CPU cache 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 base memory area of Block 0-512K.
Select "Write Back" to allow 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 .
