Dallas CRC8 Routines

[Mike, K8LH]

Has anyone ever converted Scott Dattalo's method (1-Wire Polynomial) to PBP?

crc_8
        xorwf   CRC,F           ;
        clrw                    ;
        btfsc   CRC,0           ;
        xorlw   0x5E            ; 
        btfsc   CRC,1           ; 
        xorlw   0xBC            ; 
        btfsc   CRC,2           ; 
        xorlw   0x61            ; 
        btfsc   CRC,3           ; 
        xorlw   0xC2            ; 
        btfsc   CRC,4           ; 
        xorlw   0x9D            ; 
        btfsc   CRC,5           ;
        xorlw   0x23            ; 
        btfsc   CRC,6           ; 
        xorlw   0x46            ; 
        btfsc   CRC,7           ; 
        xorlw   0x8C            ; 
        movwf   CRC             ; 
        return                  ;

It seems like a pretty good compromise between size and performance.
