MT9P031: 1/2.5-Inch 5 Mp Digital Image Sensor Serial Bus Description Stop Bit The stop bit is defined as a LOW-to-HIGH transition of the data line while the clock line is HIGH. Slave Address The 8-bit address of a two-wire serial interface device consists of 7 bits of address and 1 bit of direction. A “0” in the LSB (least significant bit) of the address indicates write mode (0xBA), and a “1” indicates read mode (0xBB). Data Bit Transfer One data bit is transferred during each clock pulse. The serial interface clock pulse is provided by the master. The data must be stable during the HIGH period of the two-wire serial interface clock—it can only change when the serial clock is LOW. Data is trans￾ferred 8 bits at a time, followed by an acknowledge bit. Acknowledge Bit The master generates the acknowledge clock pulse. The transmitter (which is the master when writing, or the slave when reading) releases the data line, and the receiver indi￾cates an acknowledge bit by pulling the data line LOW during the acknowledge clock pulse. No-Acknowledge Bit The no-acknowledge bit is generated when the data line is not pulled down by the receiver during the acknowledge clock pulse. A no-acknowledge bit is used to terminate a read sequence
