internal signal RSTF) is sufficiently held low by the external hardware to inject a Long

Hardware reset. After this occurrence, the initialization routine is not able to recognize a

Software or Watchdog bidirectional reset event, since a different source is flagged inside

WDTCON register. This phenomenon does not occur when internal FLASH is selected

during reset (EA = 1), since the initialization of the FLASH itself extend the internal reset

duration well beyond the filter delay.

Next Figure 34, Figure 35 and Figure 36 summarize the timing for Software and Watchdog

Timer Bidirectional reset events: In particular Figure 36 shows the degeneration into

Hardware reset.
