connected to pin 7 of the XPort™ and can be software configured as DCD, IN2, or OUT2.
SW1-3 is an input to the PLD which does the actual switching. The drawings represent the
logical switching function.
In this drawing, SW1-3 is OFF, which connects XPort™ pin-7 to the RS232 transceiver. The
XPort™ Configurable Pin 2 (CP2) is configured for DCD.
