The XDS110 board has a 16-pin isolated emulator connector which offers JTAG, I2C, SPI and UART interfaces and is compatible with C2000 and Sitara controlSOMs. The I2C of the MSP432 MCU is connected to EEPROM on the controlSOM through the 16-pin emulator connector and high-density connector. The MSP432 MCU UART port is connected to the bi-directional digital isolator ISO1644DWR to provide isolation and connected to the emulator connector for interfacing with the controlSOM. The DAC IC interfaces with the controlSOM MCU through the SPI on the emulator connector. The controlSOM provides a 3.3V supply to the digital isolators on the target side through the IO_TGT_V pin. Signals routed from the emulator connector are listed in Table 3-6.
