List of GPIO Pin Functions
The functions of GPIO pins are allocated to the UART interface and serial memory interface, among others, depending on the
firmware implemented to ROM and commands from the external host. This list indicates the hardware state during reset, the
software control setting immediately after the reset is released, and the functions which can be set for each GPIO pin.
When the same function name is allocated to several pins, it is not possible to select several pins to allocate the function at the
same time.

(*1) In any mode expect for the User-App mode, this will be Pull-down.
(*2) In the HCI mode, the Pull-up/Pull-down resistance will be OFF.
(*) The state of GPIO pin indicates the state when it is used in the User App mode. When the module is
started in the HCI mode, some pins may have a different state. As to the detailed state of each pin and how to
set it, refer to the Software Application Notes.
