14.5.5
On power-up the timeout sequence is as follows: First
PWRT timeout is invoked after POR has expired. Then
OST is activated. The total timeout will vary based on
oscillator configuration and PWRTE bit status. For
example, in ER mode with PWRTE bit erased (PWRT
disabled), there will be no timeout at all. Figure 14-8,
Figure 14-9
sequences.
Since the timeouts occur from the POR pulse, if MCLR
is kept low long enough, the timeouts will expire. Then
bringing MCLR high will begin execution immediately
(see Figure 14-9). This is useful for testing purposes or
to synchronize more than one PIC16F62X device
operating in parallel.
Table 14-7 shows the RESET conditions for some
special registers, while Table 14-8 shows the RESET
conditions for all the registers.

The Power Control/STATUS register, PCON (address
8Eh) has two bits.
Bit0 is BOD (Brown-out). BOD is unknown on Power-
on Reset. It must then be set by the user and checked
on subsequent RESETS to see if BOD = 0 indicating
that a brown-out has occurred. The BOD STATUS bit is
a don’t care and is not necessarily predictable if the
brown-out circuit is disabled (by setting BODEN bit = 0
in the Configuration word).
Bit1 is POR (Power-on Reset). It is a ‘0’ on Power-on
Reset and unaffected otherwise. The user must write a
‘1’ to this bit following a Power-on Reset. On a
subsequent RESET if POR is ‘0’, it will indicate that a
Power-on Reset must have occurred (V
gone too low).
