3.1.2.3 Virtual COM Port

When plugged into a USB host, the XDS110 enumerates as both a debugger and a virtual COM port. U26 and U27 are reinforced digital isolators which isolate the UART signals between the F29H850TU and the debug probe. The UART signals are then passed from the debug probe on to the USB host. By default, the F29H85x UARTA maps to the virtual COM port of the XDS110 using GPIO42 and GPIO43. Alternately, GPIO70 and GPIO71 can be used for UARTB. This is accomplished by manipulating the on-board switch S2. For the appropriate switch settings, see Section 3.1.3.2.
