12.3.1 Anticollision with 1 slot
12.1 ISO 11785 Mode
12.2 RTF Mode
12.3 Anticollision
This mode is also named TTF (Transponder Talks First).
Every time a transponder IC is activated by the field it starts executing this mode. After
waiting the maximum listening window time (see
continuously its TTF data (128-bit).
The TTF data stored in the memory will be not checked for ISO compliance, therefore
data will be sent as stored in the EEPROM.
Receiving a valid command or a switch command within the listening window sets the
transponder IC into RTF (Reader Talks First) mode.
In this mode the transponder IC reacts only to RWD request commands as presented in
Section
matching state (therefore see tables in
Section
The RWD is the master of the communication with one or multiple transponder ICs. It
starts the anticollision sequence by issuing the inventory request (see
Within the RWD command the NOS flag must be set to the desired setting (1 or 16 slots)
and add the mask length and the mask value after the command field.
The mask length n indicates the number of significant bits of the mask value. It can have
any value between 0 and 44 when 16 slots are used and any value between 0 and 48
when 1 slot is used.
The next two subsections summarize the actions done by the transponder IC during an
inventory round.
The transponder IC will receive one ore more inventory commands with NOS = '1'. Every
time the transponder ICs fractional or whole UID matches the mask value of RWD's
request it responses with remaining UID without mask value.
Transponder ICs responses are modulated by dual pattern data coding as described in
Section
13. A valid request consists of a command sent to the transponder IC being in
