</h3>
<p>
<a name="1206436"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">This command specifies the top address of an initial area of stack which is used by the ROM loader code when the application is booted. For the ST20C2, seven words above this area are required by the bootstrap and so the <font size=2 face=Courier><strong>initstack</strong></font> address must be seven words below the top of the available stack space.</font>
</p>
<p>
<a name="1206437"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">The main stack specified using the <font size=2 face=Courier><strong>stack</strong></font> command cannot be used initially, because it may be in external memory and the EMI is not guaranteed to be programmed until the ROM loader code has completed execution. Once the ROM loader code has completed, the stack is moved into the main stack as defined by the <font size=2 face=Courier><strong>stack</strong></font> command. <font size=2 face=Courier><strong>initstack</strong></font> has no effect if only a linked unit is produced.</font>
</p>
<p>
<a name="1206438"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">If the <font size=2 face=Courier><strong>initstack</strong></font> command is not given then the defaults are as follows:</font>
</p>
<ul>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206439"> </a>C2: address = Memstart (for example <font size=2 face=Courier><strong>0x80000140</strong></font> for ST20MC1),</font></p>
<p> <font size=2 face="Verdana, Arial, Helvetica, sans-serif"><li ><a name="1206440"> </a>C1: address = MostNeg (Most negative integer: <font size=2 face=Courier><strong>0x80000000</strong></font>).</font></p>
