TIME-OUT SEQUENCE
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/VPP pin must be
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.

Note 1: On wake-up, this instruction is executed. The instruction at the appropriate interrupt vector is fetched and
then executed.
2: The OST is only active (on wake-up) when the oscillator is configured for XT or LF modes.
3: The Program Counter = 0; that is, the device branches to the RESET vector and places SFRs in WDT
Reset states. This is different from the mid-range devices.
4: When BODEN is enabled, else the BOR status bit is unknown.
