DSWDTEN DSLPBOR RTCCKSEL DSWCKSEL DSWDTPS3 DSWDTPS2 DSWDTPS1 DSWDTPS0

bit 7 bit 0

Legend:

R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘0’

-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 7 DSWDTEN: Deep Sleep Watchdog Timer Enable bit

1 = DSWDT enabled

0 = DSWDT disabled

bit 6 DSLPBOR: Deep Sleep/Low-Power BOR Enable bit (does not affect operation in non Deep Sleep modes)

1 = Deep Sleep BOR enabled in Deep Sleep

0 = Deep Sleep BOR disabled in Deep Sleep

bit 5 RTCCKSEL: RTCC Reference Clock Select bit

1 = RTCC uses SOSC as reference clock

0 = RTCC uses LPRC as reference clock

bit 4 DSWCKSEL: DSWDT Reference Clock Select bit

1 = DSWDT uses LPRC as reference clock

0 = DSWDT uses SOSC as reference clock

bit 3-0 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.
