Comparator Address High Compare Bits — The comparator address high compare bits control whether the
selected comparator will compare the address bus bits [22:16] to a logic 1 or logic 0. This register byte is ignored
for XGATE compares.
0 Compare corresponding address bit to a logic 0
1 Compare corresponding address bit to a logic 1
Comparator Address Mid Compare Bits — The comparator address mid compare bits control whether the
selected comparator will compare the address bus bits [15:8] to a logic 1 or logic 0.
0 Compare corresponding address bit to a logic 0
1 Compare corresponding address bit to a logic 1
