This article presents the first of a six-part series of learning the peripheral functions of a microcontroller that is the GPIO (General-purpose Input/Output). It discusses the important peripheral, ...

This application note presents the CS4201/CS4202 audio codecs, and how to implement headphone jack sensing using the GPIO (general-purpose input/output) pins. It briefly introduced headphone jack ...

This paper provides a complete solution to the GPIO Verification for any SoC. GPIO interface is available in every ASIC. To avoid duplicate efforts and (save) time to verify the GPIO interface, we ...

For a circuit to perform a useful action, it must receive data (input) to which it will respond with an action (output). Think of a child’s toy where a press of a button turns a light turns on, and ...
