1 = V
0 = V
For “LF” Devices:
1 = V
0 = V
RTCOSC: RTCC Reference Clock Select bit
1 = RTCC uses T1OSC/T1CKI as 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 reference clock
