5.9 System Manager

5.9.1 Introduction

The System driver manages the initialization and set up of all active components, modules, and clocks of the microcontroller.

5.9.2 Supported Device Families

AVR® Dx AVR® Ex ATtiny ATmega

5.9.3 Required header files:

#include"mcc_generated_files/system/system.h"

5.9.4 Module Documentation

5.9.4.1 System Driver

5.9.4.1.1 Driver Version

System Driver Version 1.0.1
Functions

  • void SYSTEM_Initialize (void)

    This initializes the system module and must be called before any other API is called. This routine should only be called once during system initialization.

5.9.4.1.2 Function Documentation

SYSTEM_Initialize()

void SYSTEM_Initialize (void )

This initializes the system module and must be called before any other API is called. This routine should only be called once during system initialization.
