PCON Register

The Power Control (PCON) register (see Register 2-8)

contains flag bits to differentiate between a:

• Power-on Reset (POR)

• Brown-out Reset (BOR)

• Watchdog Timer Reset (WDT)

• External MCLR Reset

The PCON register also controls the Ultra Low-Power

Wake-up and software enable of the BOR.

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 7-6

Unimplemented: Read as ‘0’

bit 5

ULPWUE: Ultra Low-Power Wake-up Enable bit

= Ultra Low-Power Wake-up enabled

= Ultra Low-Power Wake-up disabled

bit 4

SBOREN: Software BOR Enable bit(1)

= BOR enabled

= BOR disabled

bit 3-2

Unimplemented: Read as ‘0’

bit 1

POR: Power-on Reset Status bit

= No Power-on Reset occurred

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

bit 0

BOR: Brown-out Reset Status bit

= No Brown-out Reset occurred

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

Note 1:

BOREN<1:0> = 01 in the Configuration Word Register 1 for this bit to control the BOR.
