On power-up the time-out sequence is as follows: First
a 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 sta-
tus of the PWRT. For example, in RC mode, with the
PWRT disabled, there will be no time-out at all.
Figure 13-11, Figure 13-12, and Figure 13-13 depict
time-out sequences on power-up.
Since the time-outs occur from the POR pulse, if the
MCLR/V
will expire. Then bringing the MCLR/V
begin execution immediately (Figure 13-14). This is
useful for testing purposes or to synchronize more than
one PIC16CXX device operating in parallel.
Table 13-10 and Table 13-11 show the reset conditions
for some special function registers, while Table 13-12
shows the reset conditions for all the registers.

The Power Control/Status Register, PCON has up to
two bits, depending upon the device. Bit0 is not imple-
mented on the PIC16C62/64/65.
Bit0 is BOR (Brown-out Reset Status bit). BOR is
unknown on Power-on Reset. It must then be set by the
user and checked on subsequent resets to see if BOR
cleared, indicating that a brown-out has occurred. The
BOR status bit is a “Don’t Care” and is not necessarily
predictable if the Brown-out Reset circuitry is disabled
(by clearing bit BODEN in the Configuration 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.
