5.1.4
On power-up, the time-out sequence is as follows: First,
the internal POR signal goes high when the POR trip
point is reached. If MCLR is high, then both the OST and
PWRT timers start. In general, the PWRT time-out is
longer, except with low frequency crystals/resonators.
The total time-out also varies based on oscillator config-
uration. Table 5-1 shows the times that are associated
with the oscillator configuration. Figure 5-5 and Figure 5-
6 display these time-out sequences.

If the device voltage is not within electrical specification
at the end of a time-out, the MCLR/V
held low until the voltage is within the device specifica-
tion. The use of an external RC delay is sufficient for
many of these applications.
The time-out sequence begins from the first rising edge
of MCLR.
Table 5-3 shows the RESET conditions for some spe-
cial registers, while Table 5-4 shows the initialization
conditions for all the registers.
