2:
This bit has no effect if the Configuration bit, WDTEN, is enabled.
Not available on devices where the on-chip voltage regulator is disabled (“LF” devices).
REGSLP: Voltage Regulator Low-Power Operation Enable bit
1 = On-chip regulator enters low-power operation when device enters Sleep mode
0 = On-chip regulator is active even in Sleep mode
LVDSTAT: Low-Voltage Detect Status bit
1 = V
0 = V
ULPLVL: Ultra Low-Power Wake-up Output bit (not valid unless ULPEN = 1)
1 = Voltage on RA0 > ~0.5V
0 = Voltage on RA0 < ~0.5V
VBGOE: Band Gap Reference Voltage (VBG) Output Enable bit
1 = Band gap reference output is enabled on pin RA1
0 = Band gap reference output is disabled
DS: Deep Sleep Wake-up Status bit (used in conjunction with RCON, POR and BOR bits to determine
Reset source)
1 = If the last exit from Reset was caused by a normal wake-up from Deep Sleep
0 = If the last exit from Reset was not due to a wake-up from Deep Sleep
ULPEN: Ultra Low-Power Wake-up Module Enable bit
1 = Ultra low-power wake-up module is enabled; ULPLVL bit indicates the comparator output
0 = Ultra low-power wake-up module is disabled
ULPSINK: Ultra Low-Power Wake-up Current Sink Enable bit
1 = Ultra low-power wake-up current sink is enabled (if ULPEN = 1)
0 = Ultra low-power wake-up current sink is disabled
SWDTEN: Software Controlled Watchdog Timer Enable bit
1 = Watchdog Timer is on
0 = Watchdog Timer is off
