2.2.2.6 PCON REGISTER

The Power Control register (PCON) contains flag bits to

allow differentiation between a Power-on Reset (POR),

Brown-Out Reset (BOR) and resets from other

sources. .

Note: On Power-on Reset, the state of the BOR

bit is unknown and is not predictable.

If the BODEN bit in the configuration word

is set, the user must first set the BOR bit on

a POR, and check it on subsequent resets.

If BOR is cleared while POR remains set,

a Brown-out reset has occurred.

If the BODEN bit is clear, the BOR bit may

be ignored.
