1. The input voltage for each ADC interface must not exceed its corresponding voltage range.
2. It is prohibited to supply any voltage to ADC pins when VBAT is removed.
3. It is recommended to use resistor divider circuit for ADC application.
3.18. USB_BOOT Interface
The module provides a USB_BOOT pin. Pulling up the USB_BOOT to VDD_EXT before powering on the
module will force the module into emergency download mode when powered on. In emergency download
mode, the module supports firmware upgrade over USB 2.0 interface.
