BUG IN PBP 2.50 & 2.50A pic16F688 ??

[Bruce]

Yep. There is a problem in the OWOUT library routine that causes a continuous loop if the
defined OSC > 8.

Open your pbppic14.lib. Scroll down to the OWOUT library routine.

Change this;

    iorwf   INDF, F     ; Set to input then wait ~10us for recovery
    decfsz  R1 + 1, F   ; Do next bit, if any
  if (OSC > 8)
    movlw    9          ; Delay 9us
    call     PAUSEUS
  endif
    goto     owoutloop

To this;

    iorwf    INDF, F     ; Set to input then wait ~10us for recovery
   if (OSC > 8)
    movlw    9           ; Delay 9us
    call     PAUSEUS
   endif
    decfsz  R1 + 1, F    ; Do next bit, if any
    goto    owoutloop

decfsz R1 + 1, F needs to be after if (OSC > 8) and just before goto owoutloop or you're stuck
in a nasty continuous loop whenver OSC > 8.
