I thought that I could add some more tests I have done: (BTW, still having
problems!!)

[PORTA : INPUT, PORTB: OUTPUT]

Main
        MOVLW   h'06'
        MOVWF   PORTB
        NOP
; up till here it is fine!
; an LED on portb<1> is on
; and the motor starts turning

; the following:

WaitHere
        CALL    Delay2
        BTFSC   PORTA,1
        GOTO    Finish
        GOTO    WaitHere

Finish
        CLRF    PORTB
        CALL    Delay2
        END

; even with a high on porta<1> there is no stopping the motor nor the LED.

I still think that there is something stopping the PIC from changing values
in portb???

Please help me!!

Thanks again.
