title: Assembly movf & movwf
body: <p>i will realize my circuit with my PIC16F84A from Microchip... so i have to put a signal from <code>PORTA,3</code> to <code>PORTB,0</code> but movwf is just working with <code>PORTB</code>... i have following code</p>
  
  <pre><code>movf        PORTA,3   ; copy PORTA,3 into registry
  movwf       PORTB,0   ; copy PORTA,3 from the registry into PORTB,0
  </code></pre>
  
  <p>so... when i give a high on <code>PORTA,3</code> it should be give a signal on <code>PORTB,0</code>....</p>
  
  <p>how can i realize that?</p>
