2.5.7.2 UART and SPI Switch

XDS110 board has one SPST, 2 position DIP Switch (S2) to set the SPI and UART signals to the emulator connector. POCI signal from digital isolator is connected to the emulator connector, when the switch (S2.1) is set to ON condition. Similarly, the receiver (Rx) signal of UART from digital isolator is connected to the emulator connector, when the switch (S2.2) is set to ON condition.
