Result of the comparator. Set when positive analog input voltage is(VPOS or 1.0v
internal regular output) higher than negative analog input voltage(VNEG) RESC is a
read only bit.
REF = 0 reference input from analog input voltage(VPOS/P4.4) pin.
REF = 1 reference input from the internal regulator output.
COMPEN = 0 Disable comparator
COMPEN = 1 Enable comparator

IRCT1 IRCX1 IRCT0 IRCX0
Mnemonic: IRC1
Address: BCh
One of the bits of IRC1 and IRC2 will be set by hardware to record the idle released condition when
the idle mode is released. IRC1 and IRC2 can be set by hardware and can be R/W by software.
IRCS1: Idle mode released by Serial port interrupt flag.
IRCT1: Idle mode released by Timer 1 interrupt flag.
IRCX1: Idle mode released by external interrupt 1 flag.
IRCT0: Idle mode released by Timer 0 interrupt flag.
IRCX0: Idle mode released by external interrupt 0 flag.

Mnemonic: IRC2
Address: BDh
One of the bits of IRC1 and IRC2 will be set by hardware to record the idle released condition when
the idle mode is released. IRC1 and IRC2 can be set by hardware and can be R/W by software.
IRCWDI: Idle mode released by Watchdog timer interrupt flag.
IRCCOMP: Idle mode released by comparator interrupt flag.
IRCDIV: Idle mode released by Divider interrupt flag.
IRCCID: Idle mode released by CID interrupt flag.
IRCX3: Idle mode released by External Interrupt 3 flag.
IRCX2: Idle mode released by External Interrupt 2 flag.
