12.8
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
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 12-6, Figure 12-
7, Figure 12-8 and Figure 12-9 depict time-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 12-8). This is useful for testing purposes or to
synchronize more than one PICmicro
operating in parallel.

Table 12-5 shows the RESET conditions for some spe-
cial function registers, while Table 12-6 shows the
RESET conditions for all the registers.
12.9
The Power Control/STATUS Register, PCON, has two
status bits that provide indication of which power-up
type RESET occurred.
Bit0 is Brown-out Reset Status bit, BOR. The BOR bit
is unknown upon a POR. BOR must be set by the user
and checked on subsequent RESETS to see if bit BOR
cleared, indicating a BOR occurred.
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.
