Preliminary

12.3.4

BROWN-OUT RESET (BOR)

The BOREN0 and BOREN1 bits in the Configuration

Word register select one of three BOR modes.

Selecting BOREN<1:0> = 10, the BOR is automatically

disabled in Sleep to conserve power and enabled on

wake-up. See Register 12-1 for the Configuration Word

definition.

A brown-out occurs when VDD falls below VBOR for

greater than parameter TBOR (see Section 15.0

“Electrical Specifications”). The brown-out condition

will reset the device. This will occur regardless of VDD

slew rate. A Brown-out Reset may not occur if VDD falls

below VBOR for less than parameter TBOR.

On any Reset (Power-on, Brown-out Reset, Watchdog

timer, etc.), the chip will remain in Reset until VDD rises

above VBOR (see Figure 12-3). If enabled, the Power-

up Timer will be invoked by the Reset and keep the chip

in Reset an additional 64 ms.

If VDD drops below VBOR while the Power-up Timer is

running, the chip will go back into a Brown-out Reset

and the Power-up Timer will be re-initialized. Once VDD

rises above VBOR, the Power-up Timer will execute a

64 ms Reset.
