Hi
I wanna discribe RB0 as a bit register!for example we can write this code in BASIC:

x0 var portb.0

so x0=RB0! and then we can use this bit like as this:
x0=0
or
0x=1

but in Assembly how we can do this?
thanks

Hi

this is my purpose:

movlw 0xfe
movwf tmp

now: if tmp.0=1 then RB0=1,delay,RB0=0,return else RB0=0,delay,return
if tmp.1=1 then RB0=1,delay,RB0=0,return else RB0=0,delay,return
....

thanks
 

Hi,

This might be what you want -

Code: 
		movlw	0xfe
		movwf	temp

		movf	temp,w
		btfss	STATUS,Z
		goto	notZero
isZero	bsf	PORTB,0
		call	Delay
		; etc

notZero	bcf		PORTB,0
		call	Delay
		;etc

Code: 
; if tmp.0=1 then RB0=1,delay,RB0=0,return else RB0=0,delay,return

                                btfsc         tmp,0
                                bsf           portb,0
                                btfss         tmp,0
                                bcf           portb,0
                                call           delay
                                bcf           portb,0
                                return

; if tmp.1=1 then RB0=1,delay,RB0=0,return else RB0=0,delay,return

                                btfsc         tmp,1
                                bsf           portb,0
                                btfss         tmp,1
                                bcf           portb,0
                                call           delay
                                bcf           portb,0
                                return
That is it !.

Hope its clear.
