S12X Debug (S12XDBGV3) Module
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).

Read: If COMRV[1:0] = 00
Write: If COMRV[1:0] = 00 and S12XDBG is not armed.
This register is visible at 0x0027 only with COMRV[1:0] = 00. The state control register 1 selects the
targeted next state whilst in State1. The matches refer to the match channels of the comparator match
control logic as depicted in
by setting the comparator enable bit in the associated DBGXCTL control register.
