4 Assignment 2: CLKCTRL - High Frequency TCD using PLL

In this assignment, the AVR128DB48 Curiosity Nano will be configured to create a high-resolution PWM signal using TCD with the PLL as a clock source.

The PLL will increase the clock frequency of OSCHF.

The output from the PLL will be used as a clock source for TCD, which will create a high-resolution PWM signal.

The starting point for this assignment is the Atmel Studio Solution Assignment2 found in Assignment2.

  • Objectives
    • Configure the PLL to use OSCHF as a clock source
    • Configure the TCD to use the PLL as a clock source and output a PWM signal
    • Visualize the PWM signal using a logic analyzer or an oscilloscope
