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 1 or logic 0.
0 Compare corresponding address bit to a logic 0
1 Compare corresponding address bit to a logic 1
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 1 or logic 0. 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 0
1 Compare corresponding data bit to a logic 1
