5.2.1. Operation

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.

5.2.2. Command Field Description

S:

The slot number “S” is encoded within the command byte as shown in Table 9.

CRC:

Communication error detection bytes.
