0000 = 1:2 (2.1 ms)
DSWDTEN: Deep Sleep Watchdog Timer Enable bit
1 = DSWDT enabled
0 = DSWDT disabled
DSBOREN: Deep Sleep BOR Enable bit
1 = BOR enabled in Deep Sleep (when using PIC18FXXJXX device)
0 = BOR disabled in Deep Sleep (does not affect operation in non Deep Sleep modes)
RTCOSC: RTCC Reference Clock Select bit
1 = RTCC uses T1OSC/T1CKI as reference clock
0 = RTCC uses INTRC as reference clock
DSWDTOSC: DSWDT Reference Clock Select bit
1 = DSWDT uses INTRC as reference clock
0 = DSWDT uses T1OSC/T1CKI as reference clock
