This section describes the programming interface of the FGPIO driver. The FGPIO driver configures the FGPIO module and provides a functional interface to build the RGPIO application.

Note

FGPIO (Fast GPIO) is only available in a few MCUs. FGPIO and RGPIO share the same peripheral but use different registers. FGPIO is closer to the core than the regular RGPIO and it's faster to read and write.

Typical use case
