DSWDTEN: Deep Sleep Watchdog Timer Enable bit
1 = DSWDT is enabled
0 = DSWDT is disabled
DSBOREN: “F” Device Deep Sleep BOR Enable bit, “LF” Device V
For “F” Devices:
1 = V
0 = V
For “LF” Devices:
1 = V
0 = V
RTCOSC: RTCC Reference Clock Select bit
1 = RTCC uses T1OSC/T1CKI as the reference clock
0 = RTCC uses INTRC as the reference clock
DSWDTOSC: DSWDT Reference Clock Select bit
1 = DSWDT uses INTRC as the reference clock
0 = DSWDT uses T1OSC/T1CKI as the reference clock
