System reset

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.
