Chapter 20 S12X Debug (S12XDBGV3) Module
20.3.2.7
There is a dedicated control register for each of the state sequencer states 1 to 3 that determines if
transitions from that state are allowed, depending upon comparator matches or tag hits, and defines the
next state for the state sequencer following a match. The three debug state control registers are located at
the same address in the register address map (0x0027). Each register can be accessed using the COMRV
bits in DBGC1 to blend in the required register. The COMRV = 11 value blends in the match flag register
(DBGMFR).
