  Pick another register as pointer, let's call it "ptr".

        clrc
        movlw   1
        btfsc   ptr,1
        movlw   4
        movwf   mask
        btfsc   ptr,0
        rlf     mask,F
        btfsc   ptr,2
        swapf   mask,F  ; or W if you need that

  Now you've got your mask value; do what you will with it.  This code
is isosynchronous, it may be shorter code to rlf mask while decfsz ptr.

  Concept not original, copied from Dimitry amongst others.
