GPIO Peripheral Bus Example for AVR Simulator Documentation

Introduction

This is the documentation for the data structures, functions, variables, defines, enums, and typedefs for the GPIO driver.

General Purpose Input/Output manages the I/O pins of the microcontroller. Each I/O line may be dedicated as a general-purpose I/O or be assigned to a function of an embedded peripheral. This assures effective optimization of the pins of a product.

The example covers various uses of the GPIO controller and demonstrates different GPIO functionalities using the peripheral bus interface. Example's operating mode:

1. Place breakpoint in gpio_tgl_gpio_pin() function in ISR
2. Open IO view and watch the value change in PVR and OVR
