... PC, and the mode pins are configured using switch positions 1 through and switch positions 1 and 2 of S1. PC Mode uses software to set up the CS4349 through I²C or USB port. When the serial port (RS232) or USB is attached and the CDB4349 software is running, PC Mode is automatically selected. ...
