... Registers are written to and read from the MT9V112 through the two-wire serial interface bus. The sensor is a serial interface slave controlled by the serial clock (SCLK), which is driven by the serial interface master. Data is transferred in and out of the MT9V112 through the serial data (S ) line. The S DATA off-chip ...
