Writing a 1 to any bit will output a high voltage on the corresponding GPIO pin.
Reserved
All reserved bits must be written as ‘0’.
GPIO 0 Input Data Register [0xC020] [R]
Figure 44. GPIO 0 Input Data Register
Register Description
The GPIO 0 Input Data register reads the input data of the GPIO pins. The GPIO 0 Input Data register reads from GPIO15 to
GPIO0 while the GPIO 1 Input Data register reads from GPIO31 to GPIO19.
Every bit represents the voltage of that GPIO pin.
GPIO 1 Input Data Register [0xC026] [R]
Figure 45. GPIO 1 Input Data Register
Register Description
The GPIO 1 Input Data register reads the input data of the GPIO pins. The GPIO 0 Input Data register reads from GPIO15 to
GPIO0 while the GPIO 1 Input Data register reads from GPIO31 to GPIO19.
Every bit represents the voltage of that GPIO pin.
