clearing the SWDTEN bit in the RCON register will have no effect)

0 = Watchdog Timer enabled/disabled by user software (LPRC can be

disabled by clearing the SWDTEN bit in the RCON register)

WINDIS

FWDT

Watchdog Timer Window Enable bit

1 = Watchdog Timer in Non-Window mode

0 = Watchdog Timer in Window mode

WDTPRE

FWDT

Watchdog Timer Prescaler bit

1 = 1:128

0 = 1:32

WDTPOST<3:0>

0 = AQEA1, AQEB1 and AINDX1 are selected as inputs to QEI1

ALTSS1

FPOR

Enable Alternate SS1 pin bit

1 = ASS1 is selected as the I/O pin for SPI1

0 = SS1 is selected as the I/O pin for SPI1

CMPPOL0

FCMP

Comparator Hysteresis Polarity (for even numbered comparators)

1 = Hysteresis is applied to falling edge

0 = Hysteresis is applied to rising edge

HYST0<1:0>

FCMP

Comparator Hysteresis Select

11 = 45 mV Hysteresis

10 = 30 mV Hysteresis

01 = 15 mV Hysteresis

00 = No Hysteresis
