4.6. I2C Interfaces
The module provides four I2C interfaces. All I2C interfaces are open drain outputs with configurable
pull-up resistors inside the module. No external pull-up resistor is needed. The reference power domain
for the interfaces is 1.85 V.

4.7. ADC Interface
The module provides one Analog-to-Digital Converter (ADC) interface which supports up to 12-bit
resolution. The pin definition is shown below:
