On power-up the time-out sequence is as follows: First
PWRT time-out is invoked by the POR pulse. When the
PWRT delay expires the Oscillator Start-up Timer is
activated. The total time-out will vary based on oscilla-
tor configuration and the status of the PWRT. For exam-
ple, in RC mode with the PWRT disabled, there will be
no time-out at all.

power-up.
Since the time-outs occur from the POR pulse, if MCLR
is kept low long enough, the time-outs will expire. Then
bringing MCLR high will begin execution immediately

The Power Control/Status Register, PCON has two sta-
tus bits that provide indication of which power-up type
reset occurred.
Bit0 is Brown-out Reset Status bit, BOR. Bit BOR is set
on a Power-on Reset. It must then be set by the user
and checked on subsequent resets to see if bit BOR
cleared, indicating a BOR occurred. However, if the
brown-out circuitry is disabled, the BOR bit is a "Don’t
Care" bit and is considered unknown upon a POR.
Bit1 is POR (Power-on Reset Status bit). It is cleared on
a Power-on Reset and unaffected otherwise. The user
must set this bit following a Power-on Reset.
