8.1.3.18 Write EAS ID
Command Code = A7h
With the command Write EAS ID a new EAS Identifier is stored in the corresponding
configuration memory. If EAS is password protected (for Set and Reset EAS) the EAS
password has to be transmitted before with the Set Password command.

8.1.3.19 Read EPC
Command Code = A8h
On the command Read EPC the I•CODE SLI-S/I•CODE SLI-S HC ICs will respond with
the EPC Data, if a Destroy EPC command had not been executed before.
