16 GPIO pins are provided in W83792D. Three kinds of registers are used to control GPIO
mechanism. GPIO Enable enables GPIO function, Output Control determines direction of the GPIO
pin, and Data/status put/get data from the pin.
CR1A GPIO Enable
CR1B/CR1D GPIO Output Control
These bits control the direction of each GPIO pins. Write 0, GPIO serves as input. Write 1, GPIO
serves as output. Default is input.
CR1C/CR1E GPIO Data/Status
Write these bits, the data will response to GPIO, set to output mode. If read this register, will return
this pin data that can input or output in this pin.
