Comparator Address Mid Compare Bits — The Comparator address mid compare bits control whether the
selected comparator compares 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
Bit 7
Comparator Address Low Compare Bits — The Comparator address low compare bits control whether the
selected comparator compares the address bus bits [7:0] 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
