CMOS Image Sensor
With Image Signal Processing
I2C Chip Interface
The serial bus interface consists of the SDA(serial data) and SCK(serial clock) pins. HV7161SP
sensor can operate only as a slave. The SCK only controls the serial interface. However, MCLK
should be supplied and RESET should be high signal during controlling the serial interface. The
Start condition is that logic transition (High to Low) on the SDA pin while the SCK
pin is at high
state. The Stop condition is that logic transition (Low to High) on the SDA pin while the SCK
pin is
at high state. To generate Acknowledge signal, the Sensor drives the SDA low when the SCK pin
is at high state. Every byte consists of 8 bits. Each byte transferred on the bus must be followed by
an Acknowledge. The most significant bit of the byte should always be transmitted first.
