Comparator Data Low Compare Bits — The comparator data low compare bits control whether the selected
comparator compares the data bus bits [7:0] 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
Comparator Data High Mask Bits — The comparator data high mask bits control whether the selected
comparator compares the data bus bits [15:8] to the corresponding comparator data compare bits. This register
is available only for comparators A and C.
0 Do not compare corresponding data bit
1 Compare corresponding data bit
