<a name="1218234"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">For secondary instructions the instruction `operation code' is shown as the memory code (the actual bytes, including any prefixes, which are stored in memory). The value is given as a sequence of bytes in hexadecimal, decoded left to right. The codes are stored in memory in `little-endian' format, with the first byte at the lowest address.</font>
</p>
<p>
<a name="1218235"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">For primary instructions the code stored in memory is determined partly by the value of the operand to the instruction. In this case, the opcode is shown as `Function x' where x is the function code in the last byte of the instruction. For example, <strong>adc</strong> (add constant) is shown as `Function 8'. </font>

<a name="1218237"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">For example, the entry for the <strong>add</strong> instruction is:</font>
