FWDTEN FWDT Immediate Watchdog Timer Enable bit
1 = Watchdog Timer always enabled (LPRC oscillator cannot be disabled.
Clearing the SWDTEN bit in the RCON register will have no effect.)
0 = Watchdog Timer enabled/disabled by user software (LPRC can be dis-
abled by clearing the SWDTEN bit in the RCON register)
WINDIS FWDT Immediate Watchdog Timer Window Enable bit
1 = Watchdog Timer in Non-Window mode
0 = Watchdog Timer in Window mode
WDTPRE FWDT Immediate Watchdog Timer Prescaler bit
1 = 1:128
0 = 1:32
WDTPOST<3:0> FWDT Immediate Watchdog Timer Postscaler bits
1111 = 1:32,768
1110 = 1:16,384

PWMPIN FPOR Immediate Motor Control PWM Module Pin Mode bit
1 = PWM module pins controlled by PORT register at device Reset
(tri-stated)
0 = PWM module pins controlled by PWM module at device Reset
(configured as output pins)
HPOL FPOR Immediate Motor Control PWM High Side Polarity bit
1 = PWM module high side output pins have active-high output polarity
0 = PWM module high side output pins have active-low output polarity
LPOL FPOR Immediate Motor Control PWM Low Side Polarity bit
1 = PWM module low side output pins have active-high output polarity
0 = PWM module low side output pins have active-low output polarity
FPWRT<2:0> FPOR Immediate Power-on Reset Timer Value Select bits
111 = PWRT = 128 ms
110 = PWRT = 64 ms
101 = PWRT = 32 ms
100 = PWRT = 16 ms
011 = PWRT = 8 ms
010 = PWRT = 4 ms
001 = PWRT = 2 ms
000 = PWRT = Disabled
ALTI2C FPOR Immediate Alternate I

C mapped to SDA1/SCL1 pins
0 = I
2
C mapped to ASDA1/ASCL1 pins
JTAGEN FICD Immediate JTAG Enable bit
1 = JTAG enabled
0 = JTAG disabled
ICS<1:0> FICD Immediate ICD Communication Channel Select bits
11 = Communicate on PGEC1 and PGED1
10 = Communicate on PGEC2 and PGED2
01 = Communicate on PGEC3 and PGED3
00 = Reserved, do not use
