Notes:

(1)The analog IC is designed to support these GPIOs configuration only. Different configuration could cause device

malfunctioning. The GPIO input configuration without pull-up or pull-down is always allowed.

Each unused GPIO inside the SiP should be configured in the OUTPUT mode low

level after the startup by software.
