1
In the case of an end-trace to reset where DBGEN=1 and BEGIN=0, the bits in this register do not change after reset.
Table 18-6. DBGCBL Field Descriptions
Field Description
Bits 7–0 Comparator B Low Compare Bits — The Comparator B Low compare bits control whether Comparator B will
compare the address bus or data bus bits [7:0] to a logic 1 or logic 0.
0 Compare corresponding address bit to a logic 0, compares to data if in Full mode
1 Compare corresponding address bit to a logic 1, compares to data if in Full mode
