The W register is subtracted (2’s com-  
plement method) from the eight bit literal  
'k'. The result is placed in the W register.  
Description:  
Subtract (2’s complement method)  
Description:  
W register from register 'f'. If 'd' is 0 the  
result is stored in the W register. If 'd' is 1  
the result is stored back in register 'f'.
