MIPI I3C 1.2
MIPI I3C is an extension of the I2C interface, so it still maintains the two-wire SCL (clock) and SDA (data) as I2C. The frequency of MIPI I3C SCL clock is defined in the spec up to 12.9 MHz, and generally it is 12.5 MHz. It supports three operating voltages: 1.2 V/1.8 V/3.3 V.
MIPI I3C is a new generation sensor interface specification that integrates multiple sensor interfaces in a unified specification, mainly to simplify sensor integration in smart phones, IoT devices, and automotive systems.
Wrong SCL/SDA or Startup mode yields incorrect decode. For channel-prefix differences, see Settings.
