Legend:
R = Readable bit W = Writable 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 DSFLT: Deep Sleep Fault Detect bit
1 = A Deep Sleep Fault was detected during Deep Sleep
0 = A Deep Sleep Fault was not detected during Deep Sleep
bit 6 BOR: BOR Deep-Sleep Wake-up Source Enable bit
1 = DSBOR event will wake device from Deep Sleep
0 = DSBOR event will not wake device from Deep Sleep
bit 5 EXT: External Interrupt Wake-up Source Enable bit
1 = External interrupt will wake device from Deep Sleep
0 = External interrupt will not wake device from Deep Sleep
bit 4 DSWDT: DSWDT Deep-Sleep Wake-up Source Enable bit
1 = DSWDT roll-over event will wake device from Deep Sleep
0 = DSWDT roll-over event will not wake device from Deep Sleep
bit 3 DSRTC: Real-Time Clock and Calendar Alarm bit
1 = The Real-Time Clock/Calendar triggered an alarm during Deep Sleep
0 = The Real-Time Clock /Calendar did not trigger an alarm during Deep Sleep
bit 2 MCLR: MCLR Deep-Sleep Wake-up Source Enable bit
1 = The MCLR Reset will wake device from Deep Sleep
0 = The MCLR
Reset will not wake device from Deep Sleep
bit 1 ICD: In-Circuit Debugger Deep-Sleep Wake-up Source Enable bit
1 = In-Circuit Debugger will wake device from Deep Sleep
0 = In-Circuit Debugger will not wake device from Deep Sleep
bit 0 DSPOR: Power-on Reset Event bit
1 = The V
DD supply POR circuit was active and a POR event was detected
0 = The V
DD supply POR circuit was not active, or was active but did not detect a POR event
Note 1: To be set in software, all bits in DSWAKE must be written to twice. The write operations do not need to be
consecutive.
