If a watchpoint is requested on a particular memory location but the data value is
irrelevant, you can program the data mask register to
so that the entire data bus value is masked.
For each value register there is an associated mask register in the same format. Setting
a bit to 1 in the mask register causes the corresponding bit in the value register to be
ignored in any comparison.
