Note : Since the default working voltage of the module's flash is 3.3 V (VDD_SPI output), the pull-up resistor
R1 of the module's internal IO45 is disabled by default. At the same time, please pay attention to ensure that
the external circuit will not pull IO45 high when the module is powered on when using IO45.
