| AN2094 discusses general-purpose input and output (GPIO) relevant topics such as GPIO drive modes, shadow registers, and GPIO interrupts to get started with PSoC 1 GPIOs. This document also provides few tips and briefs of the other resources associated with PSoC 1 GPIOs. |

General-purpose input and output (GPIO) is a very critical part of any microcontroller unit (MCU) as they form the bridge between the external world and the MCU. The type and nature of this external world bridge depends on the end application. For instance, an ADC requires a GPIO to be an analog pin whereas an I2C or SPI digital communication block requires the same GPIO to be digital. In order to properly setup this external world bridge, you need to know not only the end application but also the GPIO system of the MCU that is used. PSoC like any other controller has its own GPIO system. This application note discusses the application specific parameters of the GPIO system. Detailed technical overview of the system can be found in the respective device technical reference manual (TRM) under General Purpose I/O chapter of PSoC Core section.
