Decoding and execution of the commands
Anticollision method complying to ISO/IEC 15693. It allows the recognition of several
labels in the field which may be selected and operated in sequence.
Access to key-protected sectors is only permitted after authentication with an appropriate
key. Only one sector is opened within a session. One sector is optionally configurable
without key protection and authentication.
Memory access to the pages according to the individual access conditions programmed
