Embedded Debugger Implementation
ATtiny416 Xplained Nano contains a Mini Embedded Debugger (mEDBG) that can be used to program the ATtiny416
using Tiny Program Interface (TPI). The mEDBG also include a Virtual Com port interface over UART. Atmel Studio/
Microchip MPLAB
®
X IDE can be used as a front end for the Mini Embedded Debugger.

UPDI
The Unified Program Debug Interface (UPDI) uses one pin to communicate with the target. For further information on
how to use the programming capabilities of the mEDBG, see
