Any C languageroutine can be connected to any interrupt (trap) by calling<b><i><a href="./intArchLib.html#intConnect">intConnect</a></i>( )</b>, which resides in intArchLib. The <b><i><a href="./intLib.html#intCount">intCount</a></i>( )</b> and <b><i><a href="./intLib.html#intContext">intContext</a></i>( )</b>routines are used to determine whether the CPU is running in aninterrupt context or in a normal task context.
