Functional Description
Bit 15
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
Bit 7
Comparator Data Low Mask Bits — The Comparator data low mask bits control whether the selected
comparator compares the data bus bits [7:0] 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
