2.2.3 Virtual COM Port

When plugged into a USB host, the XDS110 enumerates as both a debugger and a virtual COM port. J101 allows the user to connect the SCI UART from the F280049C to the debug probe to be passed on to the USB host. By default, SCIA maps to the virtual COM port of the XDS110 using GPIO28 and GPIO29. Alternately, GPIO35 and GPIO37 can be used for SCIA. This is accomplished by manipulating S3, S4, and S8. For the appropriate switch settings, see the Section 2.3.
