3.14. I2C Interfaces
SC200R series module provides four I2C interfaces. All I2C interfaces are open drain signals and
therefore you must pull them up externally. The reference power domain is 1.8 V. The SENSOR_I2C
interface only supports sensors of ADSP architecture. CAM_I2C and DCAM_I2C signals are controlled by
Linux Kernel code and support connection with devices related to video output.

3.15. SPI Interfaces
SC200R series module provides three SPI interfaces, which are multiplexed from UART and GPIO
interfaces. These interfaces can only support master mode and can be used for fingerprint recognition.
