Slave Address Modes
The start bit is defined as a HIGH-to-LOW transition of the data line while the clock line
is HIGH.
The stop bit is defined as a LOW-to-HIGH transition of the data line while the clock line
is HIGH.
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 of the address indicates write mode, and a “1” indicates
read mode. As indicated above, the MT9V022 allows four possible slave addresses deter-
mined by the two input pins, S_CTRL_ADR0 and S_CTRL_ADR1.
One data bit is transferred during each clock pulse. The two-wire serial interface clock
pulse is provided by the master. The data must be stable during the HIGH period of the
serial clock—it can only change when the two-wire serial interface clock is LOW. Data is
transferred 8 bits at a time, followed by an 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.
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.
