shows the effect for RWE and RW on the comparison conditions. These bits are not useful for
Comparator Address High Compare Bits — The Comparator address high compare bits control whether the
selected comparator will compare the address bus bits [22:16] to a logic one or logic zero. This register byte is
ignored for XGATE compares.
0 Compare corresponding address bit to a logic zero
1 Compare corresponding address bit to a logic one

Debug Comparator Address High Register (DBGXAH)
Determines mapping of comparator to CPU12X or XGATE
0 The comparator is mapped to CPU12X buses
1 The comparator is mapped to XGATE address and data buses
Determines if comparator is enabled
0 The comparator is not enabled
1 The comparator is enabled for state sequence triggers or tag generation
