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

= Interrupt-on-change was asserted during Deep Sleep

= Interrupt-on-change was not asserted during Deep Sleep

bit 7

DSFLT:

Deep Sleep Fault Detected bit

= A Fault occurred during Deep Sleep, and some Deep Sleep configuration settings may have been

corrupted

= No Fault was detected during Deep Sleep

bit 6-5

Unimplemented:

Read as ‘0’

bit 4

DSWDT:

Deep Sleep Watchdog Timer Time-out bit

= The Deep Sleep Watchdog Timer timed out during Deep Sleep

= The Deep Sleep Watchdog Timer did not time out during Deep Sleep

bit 3

DSRTCC:

Real-Time Clock and Calendar Alarm bit

= The Real-Time Clock and Calendar triggered an alarm during Deep Sleep

= The Real-Time Clock and Calendar did not trigger an alarm during Deep Sleep

bit 2

DSMCLR:

MCLR Event bit

= The MCLR pin was active and was asserted during Deep Sleep

= The MCLR pin was not active, or was active, but not asserted during Deep Sleep

bit 1

Unimplemented:

Read as ‘0’

bit 0

DSPOR:

Power-on Reset Event bit(2,3)

= The VDD supply POR circuit was active and a POR event was detected

= The VDD supply POR circuit was not active, or was active but did not detect a POR event

Note 1:

All register bits are cleared when the DSCON<DSEN> bit is set.

All register bits are reset only in the case of a POR event outside Deep Sleep mode, except bit, DSPOR,

which does not reset on a POR event that is caused due to a Deep Sleep exit.

Unlike the other bits in this register, this bit can be set outside of Deep Sleep.
