Daniel,
     
     Best I can do of the top of my head is:-
     
        RLF     TEMP, W
        IORWF   TEMP, F
        RLF     TEMP, W
        IORWF   TEMP, F
     
     OR'ed result in TEMP,5
     Trashes TEMP and W
     4 cycles
     
     I'm sure somebody can do it better

Good morning -
     
I'm trying to do the following:
     
I have a byte (let's call it TEMP), and I'm trying to logically 'OR' 
together 3 of the bits within the byte.
     
ie. RESULT = (TEMP,3) or (TEMP,4) or (TEMP,5)
     
There doesn't seem to be any bit wise 'or' functions. Any ideas on how 
to implement this?
     
Thanks in advance
