19.3.1.10 Debug State Control Register 3 (DBGSCR3)
Read: Anytime
Write: Anytime when DBG not armed.
This register is visible at 0x0027 only with COMRV[1]=1. The state control register 3 selects the targeted
next state while in State3. The matches refer to the match channels of the comparator match control logic

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.
