PCON Register

The Power Control (PCON) register contains flag bits

(see Table 16-2) 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 software enable of

the BOR.

The PCON register bits are shown in Register 2-8.

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 7-5

Unimplemented: Read as ‘0’

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 Power-on Reset or Brown-out Reset

occurs)

Note 1:

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