Hi, Mackrakit,

I did a mistake:

when add the @device pic16f628 intrc_osc_noclkout
and @device 16f628 mclr_off

in the conf. window should be :

1- oscillator: intrc clockout
2- Mclr input pin

-------------------------------------------------
for several ouput pins @ port B, the story is different. I am trying to read in the data sheet of the 16f628.

regards,
