On power-up, the time-out sequence is as follows: First
PWRT time-out is invoked after the POR time delay has
expired. Then OST is activated. The total time-out will
vary based on oscillator configuration and the status of
the PWRT. For example, in RC mode with the PWRT
disabled, there will be no time-out at all. Figure 9-10,
Figure 9-11,
sequences on 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
(Figure 9-12). This is useful for testing purposes or to
synchronize more than one PIC16F716 device
operating in parallel.
Table 9-5 shows the Reset conditions for some special
function registers, while Table 9-6 shows the Reset
conditions for all the registers.

The Power Control/Status Register, PCON has two
bits.
Bit 0 is the Brown-out Reset Status bit, BOR. 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.
If the BOREN configuration bit is clear, BOR is
unknown on Power-on Reset.
Bit 1 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.
