id
(stands for: identification, R3 instruction)
The addressed device is to transmit its type description to the controller (Master).
The type description contains the type number, software version and serial number,
each separated by a blank.

Master transmits:"Slave at address 11. Send your
identification."

<ACK>
na
(stands for: new address, W1 instruction)
This instruction allows the interface to be set to a new address. The instruction is sent
to the current address. It is thus not suitable for specifying the address immediately after
system start. The device with the transferred ID is to assume the new address accompanying
the ID.

Master transmits: "Slave at address 25. Change your
address to 13."
