<strong>HC12</strong> Simula<strong>to</strong>r<br />
The 68<strong>HC12</strong> <strong>Microcontroller</strong><br />
• <strong>Microcontroller</strong> simula<strong>to</strong>r: <strong>to</strong>ol (program) that replicates<br />
<strong>the</strong> operation of a microcontroller<br />
– Learn about/ develop code without having <strong>the</strong> hardware<br />
• <strong>HC12</strong> simula<strong>to</strong>r mimics operation of <strong>HC12</strong> microcontroller<br />
– Displays and changes “registers”<br />
– Displays and changes “memory”<br />
– “Executes” code, changing contents of simulated memory/ registers<br />
according <strong>to</strong> <strong>the</strong> semantics of instructions executed<br />
