DSWDTPS<3:0>: Deep Sleep Watchdog Timer Postscale Select bits
The DSWDT prescaler is 32. This creates an approximate base time unit of 1 ms.
1111 = 1:2,147,483,648 (25.7 days)
1110 = 1:536,870,912 (6.4 days)
1101 = 1:134,217,728 (38.5 hours)
1100 = 1:33,554,432 (9.6 hours)
1011 = 1:8,388,608 (2.4 hours)
1010 = 1:2,097,152 (36 minutes)
1001 = 1:524,288 (9 minutes)
1000 = 1:131,072 (135 seconds)
0111 = 1:32,768 (34 seconds)
0110 = 1:8,192 (8.5 seconds)
0101 = 1:2,048 (2.1 seconds)
0100 = 1:512 (528 ms)
0011 = 1:128 (132 ms)
0010 = 1:32 (33 ms)
0001 = 1:8 (8.3 ms)
0000 = 1:2 (2.1 ms)
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 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
