Field Description
23–16
DBGCA
[23:16]
Comparator Address Bits [23:16]— These comparator address bits control whether the comparator compares
the address bus bits [23:16] to a logic one or logic zero.
0 Compare corresponding address bit to a logic zero
1 Compare corresponding address bit to a logic one
15–0
DBGCA
[15:0]
Comparator Address Bits[15:0]— These comparator address bits control whether the comparator compares
the address bus bits [15:0] to a logic one or logic zero.
0 Compare corresponding address bit to a logic zero
1 Compare corresponding address bit to a logic one
