Bit 15
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
comparator A. Data bus comparisons are only performed if the TAG bit in DBGACTL is clear.
0 Compare corresponding data bit to a logic zero
1 Compare corresponding data bit to a logic one
Bit 7
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
comparator A. Data bus comparisons are only performed if the TAG bit in DBGACTL is clear
0 Compare corresponding data bit to a logic zero
1 Compare corresponding data bit to a logic one
