SCCB (Serial Camera Control Bus) is a serial control bus of a camera. SCCB is similar to I2C,
because start and stop signals are same as in I2C, SCCB defines basic data transfer unit (phase),
each phase of data transfer takes one byte. SCCB contains only three kinds of transmission cycle:
1） 3-phase write transmission cycle
3-phase cycle includes: device address, register address, data
2） 2-phase write transmission cycle
2-phase cycle includes: device address, register address
3） 2-phase write transmission cycle
2-phase cycle includes: device address, data
While writing: use 3-phase write cycle directly
While Reading: first use 2-phase write cycle, then use 2-phase read cycle
More detailed information about SCCB protocol see in “OmniVision Technologies Serial Camera
Control Bus (SCCB) Specification”
