Read: If COMRV[1:0] = 01
Write: If COMRV[1:0] = 01 and DBG is not armed.
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
Register
DBGXCTL control register.
The priorities described in
final state has priority followed by the match on the lower channel number (0,1,2)
