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 one or logic zero. This register byte is
ignored for XGATE compares.
0 Compare corresponding address bit to a logic zero
1 Compare corresponding address bit to a logic one
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 one or logic zero.
0 Compare corresponding address bit to a logic zero
1 Compare corresponding address bit to a logic one
