Bob,

Could you please clarify this a bit, since I'm beginning to doubt if I 
understand this aspect of the 16F87/88. The datasheet tells me that the 
oscillator is factory tuned, but can be adjusted in the application by 
changing OSCTUNE. So I assumed that I need to write to OSCTUNE register 
_only_ when I want a different frequency than the calibrated value.
But you seem to tell me that I need to write to OSCTUNE _always_ to get 
a reliable WDT.

Regards, Rob.
