3-1-2-5 CCI single write to random location
The Master sets the sensor index value to M by designating the sensor slave address with a write request, and
designating the address (M). After that the Master can write the value in the designated register by transmitting
the data to be written. After writing the necessary data, the Master generates the Stop condition to end the
communication.

3-1-2-6 CCI sequential write starting from random location
The Master can write a value to register address M by designating the sensor slave address with a write
request, designating the address (M), and then transmitting the data to be written. After the sensor receives the
write data, it outputs an Acknowledge and at the same time increments the register address, so the Master can
write to the next address simply by continuing to transmit data. After the Master writes the necessary number of
bytes, it generates the Stop condition to end the communication.
