sequential read/write using I2C module

[X4ce]

hey!

Im using PIC16F877A's built-in I2C module with PCF8583, i have managed to read single byte but having some trouble in sequential read of bytes, my code is as follow for READING ONLY

I2CRead

	banksel	SSPCON2                ; restart I2C because i have previous
	bsf	SSPCON2,RSEN        ; i2c session on of writing
	call	CheckMSSP

	movlw	chip_write                  ; chip write byte
	call	Send_I2C_Byte
	call	CheckMSSP
	call	ACK_STAT
	
	banksel	SSPCON2      
	btfsc	SSPCON2,ACKSTAT
	goto	I2CRead

	movlw	0x02                       ; start address
	call	Send_I2C_Byte
	call	CheckMSSP
	call	ACK_STAT

	banksel	SSPCON2                  ; restart i2c
	bsf	SSPCON2,RSEN
	call	CheckMSSP

	movlw	chip_read                  ; chip read byte send
	call	Send_I2C_Byte
	call	CheckMSSP
	call	ACK_STAT

	banksel	SSPCON2                  ; receive enabled
	bsf	SSPCON2,RCEN
	call	CheckMSSP


	banksel	SSPBUF                     ; 0x02 in sec
	movf	SSPBUF,w
	movwf	sec

; section starts from here sequential read
;

	banksel	SSPCON2                     ; sending ACK instead of NACK for
	bcf	SSPCON2,ACKDT           ; further bytes to read
	bsf	SSPCON2,ACKEN

	banksel	SSPCON2                     ; receive enabled
	bsf	SSPCON2,RCEN
	call	CheckMSSP


	banksel	SSPBUF                      ; 0x03 stored in min
	movf	SSPBUF,w
	movwf	min

;sequential read end

	banksel	SSPCON2                    ; NACK bit 
	bsf	SSPCON2,ACKDT
	bsf	SSPCON2,ACKEN
	call	CheckMSSP

	bsf	SSPCON2,PEN     ; stop bit
	call	CheckMSSP

	swapf	sec,w          ; seconds in BCD for 7seg display
	andlw	0x0F
	movwf	sec1

	movf	sec,w
	andlw	0x0F
	movwf	sec0


	banksel	PORTB          ; displaying 0x03 (minutes) on PORTB 
	movf	min,w
	movwf	PORTB

	goto	I2CRead

Send_I2C_Byte
	banksel	SSPBUF
	movwf	SSPBUF
	retlw	0x00

CheckMSSP
	banksel	PIR1
	btfss	PIR1,SSPIF
	goto	$-1
	bcf	PIR1,SSPIF
	retlw	0x00

ACK_STAT
	banksel	SSPCON2
	btfsc	SSPCON2,ACKSTAT
	goto	I2C_Fail                     ; its code is not listed here
	retlw	0x00

PCF8583 datasheet suggests that you should ACK on first byte for sequential reading of next bytes.

Please suggest proper i2c module routine for seq. reading n writing

Thanks
