    PCON Register
    The Power Control (PCON) register contains flag bits
    to allow differentiation between a Power-on Reset
    (POR), a Brown-out Reset (BOR), a Watchdog Reset
    (WDT) and an external MCLR Reset.
    REGISTER 2-8:
    PCON REGISTER (ADDRESS: 8Eh)
    Note:
    BOR is unknown on POR. It must be set
    by the user and checked on subsequent
    RESETS to see if BOR is clear, indicating
    a brown-out has occurred. The BOR
    status bit is a don’t care and is not
    predictable if the brown-out circuit is dis-
    abled (by clearing the BOREN bit in the
    configuration word).

    POR: Power-on Reset Status bit
    1
    = No Power-on Reset occurred
    0
    = A Power-on Reset occurred (must be set in software after a Power-on Reset occurs)
    bit 0
    BOR: Brown-out Reset Status bit
    1
    = No Brown-out Reset occurred
    0
    = A Brown-out Reset occurred (must be set in software after a Brown-out Reset occurs)
    Legend:
    R = Readable bit
    W = Writable bit
    U = Unimplemented bit, read as ‘0’
    - n = Value at POR
    ‘1’ = Bit is set
    ‘0’ = Bit is cleared
    x = Bit is unknown
