The ATtiny817 Xplained Pro contains an Embedded Debugger (EDBG), which can be used to program and debug the ATtiny817 using Unified Program Debug Interface (UPDI). The Embedded Debugger also includes a Virtual COM Port interface over UART, a Data Gateway Interface over SPI, I2C, and two ATtiny817 GPIOs. The kit also includes an XAM extension processor to the Embedded Debugger for on-board current measurement. Atmel Studio/MPLAB® X can be used as a front-end for the Embedded Debugger.
