Description
Reserved
These bits are always read as 0. The write value
should always be 0.
Buffered Write Control for Each Area (64 Mbytes)
When writing is performed without using the cache or
in the cache write-through mode, these bits specify
whether the next bus access from the CPU waits for
the end of writing for each area.
0: The CPU does not wait for the end of writing bus
1: The CPU waits for the end of writing bus access
