Comparator Address Low Compare Bits — The Comparator address low compare bits control whether the
selected comparator will compare 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
Comparator Data High Compare Bits — The Comparator data high compare bits control whether the selected
comparator compares the data bus bits [15:8] to a logic one or logic zero. The comparator data compare bits are
only used in comparison if the corresponding data mask bit is logic 1. This register is available only for
comparators A and C.
0 Compare corresponding data bit to a logic zero
1 Compare corresponding data bit to a logic one
