Slave Address Byte
Following a start condition, the master must output a
Slave Address Byte. This byte consists of several parts:
– a device type identifier that is always ‘101x’. Where
– next two bits are ‘0’.
– next bit that becomes the MSB of the address.

then a read operation is selected. A zero selects a
write operation.
