This register controls accesses for write to the RAM by enabling or disabling the access. Controlled by this

access any area for write that is disabled against write, the corresponding RAM write monitor interrupt status is

set to "1," with no data actually written to the RAM.

Before this register can be rewritten, the RAMWRCNTPRO bit in the RAM Write Disable Protect Register must

be "0."
