title: Zilog Z80 - How to use Interrupt mode 1 (IM 1 Instruction)
body: <p>I want to use IM 1 interrupt mode on Z80. </p>
  
  <p>In Interrupt mode 1 processor jumps to 38h address in memory(am I right?) and then continues interrupt. How can I specify this in my code?
  I have read about: </p>
  
  <blockquote>
    <p>defs [,] ds [,]  This pseudo
    instruction inserts a block of  bytes into the code segment</p>
  </blockquote>
  
  <p>I need some sample source code.</p>
  
  <p>Kind Regards</p>
