SLAU748B October 2017 – September 2018 MSP432E401Y
When plugged into a USB host, the XDS-110 enumerates as both a debugger and a virtual COM port referred to as the backchannel UART. JP4 and JP5 control the selection of which UART from the MSP432E401Y is connected to the backchannel UART virtual COM port. In the default configuration, UART0 maps to the backchannel UART of the XDS-110. In the CAN jumper configuration, UART2 maps to the backchannel UART of the XDS-110.
