19.3.1.7
Each of the state sequencer states 1 to 3 features a dedicated control register to determine if transitions
from that state are allowed depending upon comparator matches or tag hits and to define the next state for
the state sequencer following a match. The 3 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 (see
19.3.1.8
Read: Anytime
Write: Anytime when DBG not armed.
This register is visible at 0x0027 only with COMRV[1:0] = 00. The state control register 1 selects the
targeted next state while in State1. The matches refer to the match channels of the comparator match
control logic as depicted in

State Control Bits — These bits select the targeted next state while in State1, 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.
