The GPIO (General Purpose Input Output) in a micro-controller is used for general purpose input or output
function. Users could use these ports to get digital signal or transmit data to any other digital device. Some
GPIOs in FS98O22 are also defined for other special functions. In this Chapter, the GPIO will be illustrated as
the GPIO function. The special functions defined in the GPIO will be illustrated in the following Chapters.
