    Microchip. There is a 9 pF, 32.768 kHz crystal in a 3.2 mm by 1.5 mm package mounted on ATtiny3217 Xplained Pro. Info:  The crystal is not connected to the device by default, as the crystal pins on the device are shared with the UART module.

  • Page 17: Embedded Debugger Implementation

    EXT1 Embedded Debugger Implementation The ATtiny3217 Xplained Pro contains an Embedded Debugger (EDBG), which can be used to program and debug the ATtiny3217 using Unified Program Debug Interface (UPDI). The Embedded Debugger also includes a Virtual COM Port interface over UART, a Data Gateway Interface over SPI, I C, and two ATtiny3217 GPIOs.

  • Page 18: Xam Configuration

    XAM Configuration On the ATtiny3217 Xplained Pro, the MCU and the MCU peripherals (e.g., extensions) are powered by their own regulator, as shown in the figure below. All the other parts of the board, mainly the embedded debugger and the accompanying Xplained Pro Analog Module (XAM), are powered from a separate regulator.
