Select Write Protect to prevent data from being written into the base memory
area of Block 0-512K. 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.
Cache Base 512K-640K
If enabled, this feature will allow the data stored in the memory area: 512K-640K to
be cached (written) into a buffer, a storage area in 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 base memory area of Block 512-640K.

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
