Mike,

I now have both data sheets and although I can see that the PUT bit is
opposite, I don't understand why I cannot set the CP bit(s). In fact, I
don't understand why the CP bits are repeated in the configuration word
in the 16F84. The programmer does support the _CONFIG directive and I
suspect this will allow both PUT and config to be set. Is that a safe
assumption?
