1.4 Acknowledge
Data transfer is performed in 8-bit sequence. A device on the system bus, which succeedingly receives
data during a period of a ninth clock cycle, puts the SDA line on “L” and returns an acknowledge signal
meaning that the data has been received.

1.5 Device addressing
The master device on the system generates a start condition to its slave device to make communication.
It continuously issues the device address of a 4-bit length, the command of a 3-bit length and the read/write
command of a 1-bit length over the SDA bus.
The upper four bits, called a device code, represent a device address and are fixed at “0110.”

1.6 Command configuration
There are eight commands by which the read/write operation of various registers is performed.
The table below lists them.
