PRODUCTION DATA
Single WRITE to defined register address shows the format of a single write to a defined register address. First, the controller issues a start condition followed by a seven-bit I 2 C address. Next, the controller writes a zero to signify that it wishes to conduct a write operation. Upon receiving an acknowledge from the target, the controller sends the eight-bit register address across the bus. Following a second acknowledge the device sets the I 2 C register address to the defined value and the controller writes the eight-bit data value. Upon receiving a third acknowledge the device auto increments the I 2 C register address by one and the controller issues a stop condition. This action concludes the register write.
