| As noted in my previous message you could use the routine from the
| piclist.com faq:
| http://www.piclist.com/techref/microchip/math/bit/mask.htm
|
| ; Convert 3-bit number (0-7) in INDEX to a 8-bit mask (00000001 ...
| ; 10000000) in BitP.
|         movfw   INDEX
|         andlw   b'00000011'     ;Start with half of the mask.
|         movwf   BitP
|         incf    BitP, W         ;The 4-bit converter
|         btfsc   BitP, 1
|         iorwf   BitP, F
|         incf    BitP, F
|         btfsc   INDEX, 2        ;Is it high 4 bits?
|         swapf   BitP, F
|
| So you make your number into a mask, then you can apply that mask to the
| number from the port.  Your value (set or clear) will show up in the
| status register, zero bit.
