PCON Register

The Power Control (PCON) register contains a flag bit

to allow differentiation between a Power-on Reset

(POR) to an external MCLR Reset or WDT Reset.

These devices contain an additional bit to differentiate

a Brown-out Reset condition from a Power-on Reset

condition.

PCON REGISTER (ADDRESS: 8Eh)

Note:

If the BOREN configuration bit is set, BOR

is ‘1’ on Power-on Reset and reset to ‘0’

when a Brown-out condition occurs. BOR

must then be set by the user and checked

on subsequent resets to see if it is clear,

indicating that another Brown-out has

occurred.

If the BOREN configuration bit is clear,

BOR is unknown on Power-on Reset.
