<strong>Max Ports:</strong> 6 8-bit bi-directional ports with programmable direction bit by bit and inverting logic
<p>
The first 3 ports have edge detection capability with polarity and enable selected individually for each bit. Edge detection can be utilized by running user interrupts. See functions <tt><a href="manual_DscEMMDIOSetState.html" class='printable' title ="DscEMMDIOSetState">dscEMMDIOSetState</a>()</tt> and <tt><a href="manual_DscEMMDIOGetState.html" class='printable' title ="DscEMMDIOGetState">dscEMMDIOGetState</a>()</tt>.
<p>
Digital I/O lines on Emerald-MM-DIO do not require configuration. Writing a 0 to any bit drives the pin high and also enables it as an input. Writing a 1 to a bit drives the pin low and forces it to an output.
<p>
A high input will read back as a 0, and a low input will readback as a 1.<p><h3><a name="Interrupts"> Interrupts </a></h3>
<p>
1 with jumper-selected IRQ level
<p>
<h3><a name="Serial_Ports"> Serial Ports </a></h3>
<p>
4 RS-232 ports with jumper-configured base addresses and IRQ levels.
<p>
Serial ports on Emerald-MM-DIO are not supported by Universal Driver.
