pow10   movwf   rC 
        addwf   rC,w 
        addwf   PCL,f 
p0      clrf    rC 
        retlw   0x01 
p1      clrf    rC 
        retlw   0x0A 
p2      clrf    rC 
        retlw   0x64 
p3      nop             ;rC=3 
        retlw   0xE8 
p4      movlw   0x27 
        movwf   rC 
        nop 
        retlw   0x10
