Slot MARKER Command [$s5]
The Slot MARKER command can be used to separately identify multiple PICCs in the RF field. The command and
response are ISO/IEC 14443-3:2001 compliant.
Slot MARKER is an optional command used to perform ISO/IEC 14443-3 Type B anticollision using the timeslot
approach. Immediately after an REQB or WUPB command with “N” greater than 1 is issued, and the ATQB response
(if any) is received, the PCD will transmit Slot MARKER commands with slot values “S” of 2 to “N” to define the start of
each timeslot for anticollision. If the random number “R” selected by the PICC matches “S” then the PICC responds
with ATQB. PICCs in the Active State are not permitted to answer this command.
