Hi.

I have a problem that if I set porta.0 and portb.2 high with porta.0=1 and porta.2=1 then they will not go high, but if I do HIGH porta.0 and HIGH porta.2 then they will.
porta.1 and porta.3 works as expected.
Anyone know why?

In the display the code below gives me:
00001111
HIGH

00000000
LOW

00001010
=1

00000000
=0


Code:
