The 'lower 6 bits' should be b'00111111'
and the 'upper 2 bits' should be....

Your example code takes the upper 6 bits from PORTA inasmuchas it clears the lower 2 bits.

Subject: [PIC]: Quick Binary logic check


Hi, just want to get a quick check of my code. I think it will work, but
I want to be sure. Basically I want to take the lower 6 bits from PortA,
the 2 upper bits from PortB, and mask them together into one byte. Will
this work?
        movf    PORTA, W
        andlw   b'11111100'
        movwf   TEMP
        movf    PORTB, W
        andlw   b'00000011'
        iorwf   TEMP, F

I changed the name of my register to TEMP so it wouldn't be quite so
confusing.

Thanks!
Josh
