Table 15: Pin Definition of the ADC
Pin Name Pin No. Description
ADC0 45 General purpose analog to digital converter
ADC1 44 General purpose analog to digital converter
The following table describes the characteristic of the ADC function.
Table 16: Characteristic of the ADC
Parameter Min. Typ. Max. Unit
ADC0 Voltage Range 0.3 VBAT_BB V
ADC1 Voltage Range 0.3 VBAT_BB V
ADC Resolution 15 bits
1. ADC input voltage must not exceed VBAT_BB.
2. It is prohibited to supply any voltage to ADC pinswhen VBAT is removed.
3. It is recommended to use resistor divider circuit for ADC application.
3.14. Network Status Indication
The network indication pins can be used to drive network status indication LEDs. The module provides
two pins which are NET_MODE and NET_STATUS. The following tables describe pin definition and logic
level changes in different network status.
