PRODUCTION DATA
Single READ from a defined register address shows the format of a single read from 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 conducts 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 internal I 2 C register number to the defined value. Then the controller issues a repeat start condition and the seven-bit I 2 C address followed by a one to signify that it conducts a read operation. Upon receiving a third acknowledge, the controller releases the bus to the device. The device then returns the eight-bit data value from the register on the bus. The controller does not acknowledge (nACK) and issues a stop condition. This action concludes the register read.
