Hello Everyone,

I am new to pics.  I was reading tin "Easy Pic n'" and came across some
code.

start   movlw   0x00

        tris    portb

        clrf    portb   ;outputs to LO

If I understand this code correctly it sets all of the pins to output.
Thats fine, then it tells them to go active low.

If I don't understand it, then when we set portb to outputs, they output
randomly as high and low logic, causing us to do the clrf portb to force
them to active low?

Which is it?

Brian
