Hello!

I have asked the question before but here is
some fact:

Device: 16F870
In the config line the DEBUG is set to OFF
PORTB 0-3 is output  PORTB 4-7 is input.

To RB6 is a push-button switch connected
to ground and pulled up to + 5V via 10k
resistor.
When i pushing on the button the whole
programm stops running.
If I changed this switch to RB4 the programm
will works ok!
Of course, I can use I /O pin RB4 but I want
to know how the problem will be solved out.
I can=B4t find anything about this in Microchips
directions either.

Maybe, any members of this list has experience
of the problem and will share that with me ?

Regards
