5.2.1

BOR IS ALWAYS ON

When the BOREN bits of Configuration Words are

programmed to ‘11’, the BOR is always on. The device

start-up will be delayed until the BOR is ready and VDD

is higher than the BOR threshold.

BOR protection is active during Sleep. The BOR does

not delay wake-up from Sleep.

5.2.2

BOR IS OFF IN SLEEP

When the BOREN bits of Configuration Words are

programmed to ‘10’, the BOR is on, except in Sleep.

The device start-up will be delayed until the BOR is

ready and VDD is higher than the BOR threshold.

BOR protection is not active during Sleep, but device

wake-up will be delayed until the BOR can determine

that the VDD is higher than the BOR threshold. The

device wake-up will be delayed until the BOR is ready.

5.2.3

BOR CONTROLLED BY SOFTWARE

When the BOREN bits of Configuration Words are

programmed to ‘01’, the BOR is controlled by the

SBOREN bit of the BORCON register. The device

wake from Sleep is not delayed by the BOR ready con-

dition or the VDD level.

BOR protection begins as soon as the BOR circuit is

ready. The status of the BOR circuit is reflected in the

BORRDY bit of the BORCON register.

BOR protection is unchanged by Sleep.

5.2.4

BOR ALWAYS OFF

When the BOREN bits of Configuration Word 2 are

programmed to '00', the BOR is always disabled. In this

configuration, setting the SBOREN bit will have no

effect on the BOR operation.
