PCON Register
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.
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.
If the BOREN Configuration bit is clear,
BOR is unknown on Power-on Reset.
