4.4 CPU - Central Processor Unit
4.4.1 Introduction
The MPLAB® Code Configurator (MCC) Melody Central Processing Unit (CPU) system driver generates APIs to support CPU-specific peripheral functionality on ATmegaxxx target MCUs.
The main function of the CPU core is to ensure correct program execution. The CPU must therefore be able to access memories, perform calculations, control peripherals, and handle interrupts
