It does not matter whether the data area exists or what data is contained.
Legend:
SLA
slave address
5 bits
0x00…0x1F = 0…31
ST
slave type
1 bit
0 = single slave or A slave
1 = B slave (= addition of 0x20 or 32 to the slave address)
UID

0x0000…0xFFFF = 0…65535
The user ID ensures clear identification of the commmand response data
of the command request data sent before. The user can assign any user
ID in the command request. The AS-i master reflects the user ID from the
command request into the corresponding command response.
If the requested slave address (SLA) is not in the list of activated slaves (LAS), the new
parameters are stored in the AS-i master despite error message (error code 0x0A). If an AS-i
slave with this address is added to the AS-i network at a later point, the slave automatically
adopts the saved parameters.
