[SLAVE ADDRESS]
After the START condition, a SLAVE ADDRESS is sent. If the transmitted slave address matches an
address of one of the device, the designated slave pulls the SDA line to LOW .
AK6002A

The most significant four bits of the slave address are fixed as "1010". The next
three bits are S0, S1 and S2 device address bits. These three bits identify the specific
device on the bus. They is set by the hard wired input pins (S0 pin, S1 pin and S2 pin).
Therefore a total of eight devices can be connected to the same bus.
AK6004A

The most significant four bits of the slave address are fixed as "1010". The next two
bits are S2, S1 device address bits. These two bits identify the specific device on the
bus. They is set by the hard wired input pins (S1 pin and S2 pin). Therefore a total of
four devices can be connected to the same bus.
The next one bit is the most significant bit of the memory address.
AK6008A

The most significant four bits of the slave address are fixed as "1010". The next
three bits are the most significant three bits of the memory address.
The last bit of the slave address (R/W bit) defines whether a write or read condition is requested by
the master. A "1" indicates that the read operation is to be executed. A "0" indicates that the write
operation is to be executed.
