<h3>Description</h3>
<p>
The RadioBox module sets the behaviour of an array of groups (currently
required to be type int) to that of a radiobox i.e. only one item can be
selected at any particular time. It changes the set array according to
the input in selectedItem or vice versa. The set
array contains one value set to 1 and 0 values for all other values.
</p>
<h3>Inputs</h3>
<p>
<i><b>active</b></i>
</p>
<p>
Active is a flag which switches the module on or off.
</p>
<p>
<i><b>&set[]</b></i>
</p>
<p>
Array of integers that contains a single value 1 on the position given by
selectedItem. All other values are set to 0.
</p>
<h3>Outputs</h3>
<p>
<i><b>selectedItem</b></i>
</p>
<p>
Contains the index of the currently selected item.
</p>
<p>
<i><b>previousItem</b></i>
</p>
<p>
Contains the index of the previously selected item.
</p>
<h3>Files</h3>
<p>
<I>iac_proj/radiobox/rdbxmods.v</I> contains the RadioBox module V definition.
</p>
<h3>Other Notes</h3>
<p>
The low-level RadioBoxMods library containing the module RadioBox does not
specify a process. By default the <tt>express</tt> process will be used.
