Common Parameters
ATA5590
All commands are based on common parameter bits:
Additionally, some commands support pointers to EEPROM addressing.
Figure 10-1. Principle of the Selection Flow
If the select bit is set in the parameter field (parameter(0)) or implemented in the command
(short commands), then the ID_s, ID, and pre_select flags (status1) influence the execution flow
as shown in
Notes:
• Define the encoding schema of the backscatter modulation — mod(1) and mod(0)
• Define if the tag has to consider the results of the arbitration or group_select mechanism
stored in status2, the select bit.
1. All anticollision commands check only the pre_select flag of status2, if required (select bit).
2. If a deterministic arbitration was activated before the following read and write commands,
check only the arbitration status bit, otherwise, the pre_select bit.
