DSWDTEN DSBOREN RTCOSC DSWDTOSC 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 is enabled
0 = DSWDT is disabled
bit 6 DSBOREN: Deep Sleep/Low-Power BOR Enable bit (does not affect operation in non Deep Sleep modes)
1 = Deep Sleep BOR is enabled in Deep Sleep
0 = Deep Sleep BOR is disabled in Deep Sleep
bit 5 RTCOSC: RTCC Reference Clock Select bit
1 = RTCC uses SOSC as a reference clock
0 = RTCC uses LPRC as a reference clock
bit 4 DSWDTOSC: DSWDT Reference Clock Select bit
1 = DSWDT uses LPRC as a reference clock
0 = DSWDT uses SOSC as a 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.
