(DBGXCTL)”. Comparators must be enabled by setting the comparator enable bit in the associated
DBGXCTL control register.
19.3.1.11 Comparator Register Descriptions
Each comparator has a bank of registers that are visible through an 8-byte window in the DBG module
register address map. Comparators A and C consist of 8 register bytes (3 address bus compare registers, 2
data bus compare registers, 2 data bus mask registers and a control register).
Comparators B and D consist of 4 register bytes (3 address bus compare registers and a control register).
Each set of comparator registers is accessible in the same 8-byte window of the register address map and
can be accessed using the COMRV bits in the DBGC1 register. If the Comparators B or D are accessed
through the 8-byte window, then only the address and control bytes are visible, the 4 bytes associated with
data bus and data bus masking read as 0 and cannot be written. Furthermore the control registers for
comparators B and D differ from those of comparators A and C.

State Control Bits — These bits select the targeted next state while in State3, based upon the match event.
The trigger priorities described in
the lower channel number (0,1,2,3) has priority. The SC[3:0] encoding ensures that a match leading to final state
has priority over all other matches.
