2.2.2.6 PCON Register

The Power Control (PCON) register (see Table 12-3)

contains flag bits to differentiate between a:

• Power-on Reset (POR)

• Wake-up Reset (WUR)

• Brown-out Detect (BOD)

• Watchdog Timer Reset (WDT)

• External MCLR Reset

The PCON register also controls the Ultra Low-Power

Wake-up and software enable of the BOD.

The PCON register bits are shown in Register 2-6.

Unimplemented: Read as ‘0’

ULPWUE: Ultra Low-Power Wake-up Enable bit

1 = Ultra Low-Power Wake-up enabled

0 = Ultra Low-Power Wake-up disabled

SBODEN: Software BOD Enable bit(1)

1 = BOD enabled

0 = BOD disabled

WUR: Wake-up Reset Status bit

1 = No Wake-up Reset occurred

0 = A Wake-up Reset occurred (must be set in software after a Power-on Reset occurs)

Unimplemented: Read as ‘0’

POR: Power-on Reset Status bit

1 = No Power-on Reset occurred

0 = A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)

BOD: Brown-out Detect Status bit

1 = No Brown-out Detect occurred

0 = A Brown-out Detect occurred (must be set in software after a Brown-out Detect occurs)

Note 1: BODEN<1:0> = 01 in the Configuration Word register for SBODEN to control the

Brown-out Detect module.

Legend:

R = Readable bit

- n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared x = Bit is unknown
