This register is visible at 0x0027 only with COMRV[1:0] = 01. The state control register 2 selects the
targeted next state whilst in State2. The matches refer to the match channels of the comparator match
control logic as depicted in
enabled by setting the comparator enable bit in the associated DBGXCTL control register.
The trigger priorities described in
on 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.
