hi again... :rolleyes:

i'm having a problem initialising my ports with the following code on the 16F88, and all i seem to get is this error message;

Register in operand not in bank 0. Ensure that bank bits are correct.

when i am SURE i have selected bank 1 where those particular registers are located.

Code:
START

INITIALIZE_PORTS

	BCF 	STATUS,RP1			; select bank 1
	BSF 	STATUS,RP0
	MOVLW	B'00000101'			; setting up PORTA
	MOVWF 	TRISA
	MOVLW	B'00100000'			; setting up PORTB
	MOVWF 	TRISB
	MOVLW 	D'39'				; 31250 baud rate
	MOVWF 	SPBRG 				
	MOVLW 	B'00000100'			; set up high speed BRGH and disable tx pin
	MOVWF 	TXSTA
	MOVLW	B'10010000'			; set up asynchronous reception
	MOVWF	RCSTA
thanks for your help on this confusing matter.
