PRODUCTION DATA
To write on the I2C bus, the leader device sends a START condition on the bus with the address of the 7-bit follower device. Also, the last bit (the R/W bit) is set to 0b, which signifies a write. After the follower sends the acknowledge bit, the leader device then sends the register address of the register to be written. The follower device sends an acknowledge (ACK) signal again which notifies the leader device that the follower device is ready. After this process, the leader device sends 8-bit write data and terminates the transmission with a STOP condition.
