Configuration
July 2008 Revision 4.2 27/62
Only one gate is defined to be the master who emits a synchronization burst to the slaves
in close proximity.
The other gates, configured as slave, synchronize themselves on the master’s burst, and if
they have a matching ID, scan the configured chip.

Synchronization burst: start burst to synchronize the gates (Period of Tscan ms)
Processing time (Pt): depends on the number of chip types to be detected. The faster is
when only one chip type is selected (see Table 2: Scanning Duration).
The Tscan period is optimized according to the number of slaves and number of chips to
detect.
5.2.2 Special Synchronization Mode
This mode has an identical Master/Slave configuration as described in the Standard
Synchronization mode.
Synchronization process:
1- The master scans the configured chip, then send the synchronization burst to Slave1
2- Slave1 scan the configured chip, then send the synchronization burst to Slave2
Default configuration of the L-SP2 is set to Master.
Only used in ISO15693 (C370/C370-L/Tag-It) AFI mode with Read-Memory activated.
