Switching Between Programming and Power Options with Xplained Mini

AVR® Microcontroller (MCU): Switching Between Programming and Power Options with Xplained Mini
Overview
In this video:
Alternate between ISP and debugWIRE interface (toggling the power after using SPI to enable the Debug Wire Enable (DWEN) Fuse).
Switch to ISP from debugWIRE: While debugging, selecting Disable debugWIRE and close now allows to select ISP.
Open the Programming dialog box in ISP mode to read the fuse settings.
Program the Clout Out (CKOUT) fuse to put the AVR® MCU clock out on the COUT pin.
Run the ATmega328PB Xplained Mini at:
5 V - reading a clock frequency of 16 MHz.
3 V - reading a clock frequency of 8 MHz.
Understand speed vs. voltage of the AVR MCU from the datasheet.
If you need to work with Microchip Support staff directly, you can submit a technical support case. Keep in mind that many questions can be answered through our self-help resources, so this may not be your speediest option.
