On power-up the time-out sequence is as follows: First
PWRT time-out is invoked after the POR time delay has
expired. Then OST 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 9-11,
Figure 9-12,
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 9-13). This is useful for testing purposes or to
synchronize more than one PIC16CXXX device
operating in parallel.
Table 9-5 shows the Reset conditions for some Special
Function Registers, while Table 9-6 shows the Reset
conditions for all the registers.
