Channel Priority Number
When round-robin arbitration is enabled (PRICTRL.RREN=1) for priority level, this register holds the channel number of the last EVSYS channel being granted access as the active channel with priority level. The value of this bit group is updated each time the INTPEND or any of CHINTFLAG registers are written.
When static arbitration is enabled (PRICTRL.RREN=0) for priority level, and the value of this bit group is nonzero, it will not affect the static priority scheme.
This bit group is not reset when round-robin scheduling gets disabled (PRICTRL.RREN written to zero).
