Time-out Sequence
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 conguration and the status of
the PWRT. For example, in RC mode with the PWRT
disabled, there will be no time-out at all. Figure 10-7,
out 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 10-9). This is useful for testing purposes or to
synchronize more than one PIC16CXXX family device
operating in parallel.
Table 10-5 shows the reset conditions for some special
function registers, while Table 10-6 shows the reset
conditions for all the registers.
10.9
Power Control/Status Register
(PCON)
The Power Control/Status Register, PCON has up to
two bits, depending upon the device.
Bit0 is Brown-out Reset Status bit, BOR. Bit BOR is
unknown 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. The BOR bit
is a "Don’t Care" bit and is not necessarily predictable
if the Brown-out Reset circuitry is disabled (by clearing
bit BODEN in the Conguration Word).
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.

Note 1:
When the wake-up is due to an interrupt and the GIE bit is set, the PC is loaded with the interrupt vector (0004h).
