Legend: HS = Hardware Settable bit
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 15-9 Unimplemented: Read as ‘0’
bit 8 DSINT0: Interrupt-on-Change bit
(1)
1 = External Interrupt 0 was asserted during Deep Sleep
0 = External Interrupt 0 was not asserted during Deep Sleep
bit 7 DSFLT: Deep Sleep Fault Detected bit
(1)
1 = A Fault occurred during Deep Sleep and some Deep Sleep configuration settings may have been
corrupted
0 = No Fault was detected during Deep Sleep
bit 6-5 Unimplemented: Read as ‘0’
bit 4 DSWDT: Deep Sleep Watchdog Timer Time-out bit
(1)
1 = The Deep Sleep Watchdog Timer timed out during Deep Sleep
0 = The Deep Sleep Watchdog Timer did not time out during Deep Sleep
bit 3 DSRTC: Real-Time Clock and Calendar Alarm bit
(1)
1 = The Real-Time Clock and Calendar triggered an alarm during Deep Sleep
0 = The Real-Time Clock and Calendar did not trigger an alarm during Deep Sleep
bit 2 DSMCLR: Deep Sleep MCLR
Event bit
(1)
1 = The MCLR pin was asserted during Deep Sleep
0 = The MCLR
pin was not asserted during Deep Sleep
bit 1 Unimplemented: Read as ‘0’
bit 0 DSPOR: Power-on Reset Event bit
(2)
1 = The VDD 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: This bit can only be set while the device is in Deep Sleep mode.
2: This bit can be set outside of Deep Sleep.
