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 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
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
