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. Network Status Indication
The network indication pins can be used to drive network status indication LEDs. The module provides
two network indication pins: NET_MODE and NET_STATUS. The following tables describe the pin
definition and logic level changes in different network status.
