1. The master sends the write-node slave address and 8-bit address, just as in the write
2. The master sends a start bit and the read-mode slave address.
3. The master clocks out the register data 8 bits at a time.
4. The master sends an acknowledge bit after each 8-bit transfer.
5. The register address is auto-incremented after every 16 bits transferred.
6. The data transfer is stopped when the master sends a no-acknowledge bit.
Registers are written to and read from the MT9T031 through the two-wire serial inter-
face bus. The MT9T031 is a serial interface slave and is controlled by the serial clock
(SCLK), which is driven by the serial interface master. Data is transferred into and out of
the MT9T031 through the serial data (S

A typical read or write sequence begins with the master sending a start bit. After the start
bit, the master sends the slave device's 8-bit address. The last bit of the address deter-
mines if the request is a read or a write (“0” indicates a write and a “1” indicates a read).
The slave device acknowledges its address by sending an acknowledge bit back to the
master.
If the request was a write, the master then transfers the 8-bit register address to which a
write should take place. The slave sends an acknowledge bit to indicate that the register
address has been received. The master then transfers the data 8 bits at a time, with the
slave sending an acknowledge bit after each 8 bits.
The MT9T031 uses 16-bit data for its internal registers, thus requiring two 8-bit transfers
to write to one register. After 16 bits are transferred, the register address is automatically
incremented so that the next 16 bits are written to the next register address. The master
stops writing by sending a start or stop bit.
A typical read sequence is executed as follows:
