    Time-out Sequence and Power-down
    Status Bits (TO/PD)
    and Figure 8-13) the time-out sequence is as follows:
    First PWRT time-out is invoked after a POR has
    expired. Then the OST is activated. The total time-out
    will vary based on oscillator configuration and PWRTE
    configuration bit status. For example, in RC mode with
    the PWRT disabled, there will be no time-out at all.
    TABLE 8-5
    TIME-OUT IN VARIOUS
    SITUATIONS
    Since the time-outs occur from the POR reset pulse, if
    MCLR is kept low long enough, the time-outs will
    expire. Then bringing MCLR high, execution will begin
    immediately (Figure 8-10). This is useful for testing
    purposes or to synchronize more than one PIC16F8X
    device when operating in parallel.
    Table 8-6 shows the significance of the TO and PD bits.
    Table 8-3 lists the reset conditions for some special
    registers, while Table 8-4 lists the reset conditions for
    all the registers.

    Reset on Brown-Out
    A brown-out is a condition where device power (VDD)
    dips below its minimum value, but not to zero, and then
    recovers. The device should be reset in the event of a
    brown-out.
    To reset a PIC16F8X device when a brown-out occurs,
    external brown-out protection circuits may be built, as
