2.6.1 SW1-2 Options
SW1-2 controls the routing of the CP1 (Configurable Pin 1) signal from the XPort™. CP1 is
connected to pin 6 of the XPort™ and can be software configured as CTS, IN1, OUT1, or
LED1. SW1-2 is an input to the PLD which does the actual switching. The drawings
represent the logical switching function.
In this drawing, SW1-2 is OFF, which connects XPort™ pin 6 to the RS232 transceiver. The
XPort™ Configurable Pin 1 (CP1) is configured for CTS.
