Hi friends
I am confused with the clrw command in pic assembly language,

If I need to clear "w" Register in a program,
I can use movlw 0h
then why microchip added an instruction CLRW in their instruction set?
is it an extra command or it has any special need? 'Z' flag is affected by both movlw and clrw !!!
 

Re: CLRW

No, they are not the same.

CLRW affects the Z flag, MOVLW does not.

Cheers,
