I've spent more time, too much time, with the 14K22 today
and still not getting anywhere. Twiddled with bits all over the
place

The odd thing is that whatever I do there's always 250kHz on
Osc2. It's like this frequency-setting at the start of main code is
never executed

         movlw   b'00010000'
;                  0            Run
;                   110         8MHz
;                      -        OSTS
;                       -       freq stable
;                        00     internal RC (set by Config1 FOSC)
         movwf   osccon

and possibly that the following port initialisation doesn't either

I get no programming errors in situ with ICSP or on a breadboard,
and tried 4 new chips out of the tube.

Main code is at 0x100 and start vector is at 0x00, pointing to 0x100

Any thoughts ? What am I missing ?

TIA

Joe
