Below is my initialisation code.

initialise	clrf porta
		clrf portc

		bsf status,5	<------------ Bank 1

		movlw b'10000000'
		movwf ansel
		movlw b'00110000'
		movwf adcon1

		IF DEBUG
		movlw b'11111011'
		ELSE
		movlw b'11111000'
		ENDIF

		movwf trisa

		movlw b'11001011'
		movwf trisc

		movlw b'11010011'
		movwf option_reg

		clrf wpua
		clrf ioca

		bcf status,5		<--------- Bank 0

		movlw b'00000111'
		movwf cmcon

		clrf t1con

		retlw 00h


The same problem is happening in PORTA,2.

Cheers

Ravi
