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. .
REGISTER 2-6:
PCON REGISTER (ADDRESS 8Eh)
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.

= No Brown-out Reset occurred
0
= A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)
