<strong>GMM-24:</strong> 3 8-bit bidirectional ports (1 82C55 chip) <br>
<strong>GMM-48:</strong> 6 8-bit bidirectional ports (2 82C55 chips)
<p>
Digital I/O ports on Garnet-MM require direction to be set with <tt><a href="manual_DscDIOSetConfig.html" class='printable' title ="DscDIOSetConfig">dscDIOSetConfig</a>()</tt> before use. One configuration byte is required for each 82C55 chip.
<p>
All DIO lines power-up in input mode and have readback capability.
<p>
DIO lines on this board do not have pull-up resistors.<p><h3><a name="Interrupts"> Interrupts </a></h3>
<p>
<strong>GMM-24:</strong> 1; source is digital I/O bit C0 of the 82C55 chip <br>
<strong>GMM-48:</strong> 2; sources are digital I/O bit C0 of each 82C55 chip Interrupt levels are configured with jumpers.
