RRF and RLF instruction in ASM

HC595 MACRO Var,Var1

	Local Loop		; Local Label
	MOVLW .8		; Transfer 8 bits
  	MOVWF Var1		; Initializing counter

Loop	
	RLF Var,f	; Rotate "Var" one place to the left
	BTFSS STATUS,C	; Is carry 1?
	BCF Bits		; If not set data line to 0
	BTFSC STATUS,C	; Is carry 0?
	BSF Bits		; If not set data line to 1

	BSF Clock		; Generate one clock
	BCF Clock		;

	DECFSZ Var1,f	; Has 8 bits been sent?
	GOTO Loop		; If not, repeat

	BSF Latch		; If all 8 bits have been sent, set latch
	BCF Latch

	ENDM
