14 The GPIOs are organized in port/bank, each p 14 The GPIOs are organized in port/bank, each port consists of 32 GPIOs.
15 As the GPIO controller is embedded in the PI 15 As the GPIO controller is embedded in the PIN controller and all the
16 GPIO ports share the same IO space with PIN 16 GPIO ports share the same IO space with PIN controller, the GPIO node
