ATA5558 [Preliminary]

Tag Configuration Register  
The internal tag configuration register holds a shadow copy of the configuration settings stored  
in the system memory’s block 63. It is refreshed after every POR cycle (RF field on), Reset to  
Ready or Write to block 63.

Notes:  
ITF =Interrogator Talks First Mode  
PM = Public Mode  
EAS = Electrical Article Surveillance  
NRZ = Non Return to Zero  
(1) If master key = 6hex then all test modes are ignored and password protection enabled  
(2) If DDR = 1 and master key = 6hex or 9hex then data rate = fast, otherwise slow  
R = reserved for future use, should be set to 0  
x = don't care state  
3. Transmission Protocol  
The transmission protocol defines the mechanism to exchange commands and data between  
the interrogator and the tags. In all but the Public and EAS Mode, the interrogator has complete  
control over the communication flow – all data transmission being synchronized to interrogator  
commands and the interrogator field clock – “Interrogator Talks First” (ITF) principle. This means  
that a tag does not transmit data, unless it has received and properly decoded an interrogator  
command.  
The protocol is based on an exchange of  
• commands from the interrogator to the tag (Downlink mode)  
• and response from the tag to the interrogator (Uplink mode)
