2.1.2.3 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 F28P550SJ9 to the debug probe to be passed on to the USB host. By default the F28P55x SCIA maps to the virtual COM port of the XDS110 using GPIO28 and GPIO29. Alternately, GPIO15 and GPIO56 can be used for SCIB. This is accomplished by manipulating the on-board switch S2. For the appropriate switch settings, see Section 2.1.3.2.
