AN86439 explains how to effectively use PSoC® 4 and PSoC Analog Coprocessor GPIO pins with various use case examples to demonstrate their features. Major topics in this application note include GPIO basics, configuration options, mixed-signal use, interrupts, and low-power behavior.

Introduction

PSoC has powerful and flexible general-purpose I/O (GPIO) pins that provide more features than traditional MCUs. In PSoC, the GPIOs are controlled not only by configuring the registers in the firmware, similar to traditional MCUs, but are also driven by custom digital logic and analog block signals. This application note explains the basics of PSoC 4 GPIO pins and demonstrates techniques for using them effectively for different functions.
