2.0 PIN DESCRIPTIONS
This section describes the operation of the DLP-2232H pins. The function of the I/O pins is
determined by the configuration that is stored in the EEPROM connected to the FT2232H IC.
The following table details the function of each pin for the specified mode. Note that the
convention used throughout this document for active low signals is the signal name followed by
a #. Pins marked ** default to tri-stated inputs with an internal 75K Ohm (approx) pull up
resistor to VCCIO (3.3V). Pins marked *** may require mode select jumper configuration. This is
explained in section 2.1.
