Cache Base 0–512K
If enabled, this feature allows the data stored in the 0–512K memory
area to be cached (written) into a buffer, a storage area in static DROM
(SDROM), or written into L1, L2 cache inside the CPU to increase CPU
operation speed. 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 the CPU to write back data 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 (default).
Cache Base 512K–640K
If enabled, this feature allows the data stored in the 512K–640K 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 increase
CPU operation speed. 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. Select

Cache Extended Memory
If enabled, this feature allows the data stored in the extended memory
area 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 increase
CPU operation speed. 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 system memory area above 1 MB. Select Write
Back to allow the CPU to write back data 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 (default).
