However only the boards listed below have Solo type user interrupt capability. For each of these boards, all valid combinations for the DSCUSERINT structure are listed along with a description of the behavior. See the user interrupt example program in each board's example program set for more explanation.

<p>
<a href="manual_Emerald-MM-DIO.html" class='printable' title ="Emerald-MM-DIO">Emerald-MM-DIO</a> has no counter/timers. It may be programmed to generate interrupts when a change of state is detected on digital I/O lines on ports 0-2. All parameters for dscuserint are ignored and should be left at 0. However the function must still be called to initiate interrupts. The user interrupt operation is configured with <tt><a href="manual_DscEMMDIOSetState.html" class='printable' title ="DscEMMDIOSetState">dscEMMDIOSetState</a></tt>(). See page 123 for information on this function.<p><h3><a name="Garnet-MM-24,_Garnet-MM-48"> <a href="manual_Garnet-MM.html" class='printable' title ="Garnet-MM">Garnet-MM-24</a>, <a href="manual_Garnet-MM.html" class='printable' title ="Garnet-MM">Garnet-MM-48</a> </a></h3>
<p>
On <a href="manual_Garnet-MM.html" class='printable' title ="Garnet-MM">Garnet-MM</a>, user interrupts are generated by the digital I/O lines C0 on each 82C55. There is no hardware configuration required, so all values for dscuserint are 0. <a href="manual_Garnet-MM.html" class='printable' title ="Garnet-MM">Garnet-MM-24</a> has one interrupt using C0 on chip no. 1, while <a href="manual_Garnet-MM.html" class='printable' title ="Garnet-MM">Garnet-MM-48</a> has two interrupts using C0 on each chip.

<ul><li> In these modes, if clksource = 0 (external clock), then rate = 0 and the user must program the counter/timer(s) beforehand for the desired rate using dscCounterDirectSet(), since the driver has no way of knowing the input frequency in order to determine the proper divider.
