EM4223  
Reader Command  
Transponder Operation in  
ISO Mode  
Transponder Operation in  
Fast SupertagMode  
INIT_ROUND  
Initialises the start of the arbitration sequence  
and tells the Transponder over how many slots  
to randomise the transmit slot selection.  
Configures the Transponder to transmit the  
SUID data or the full 128 bit User Data to the  
Reader dependent on the SUID parameter in  
the command. Moves the Transponder from the  
READY to the ROUND_ACTIVE states if the  
Transponders AFI matches the AFI in the  
command or if the AFI in the command = 0x00 .  
If the AFI in the command is non-zero and does  
not match the AFI in the Tag, causes the Tag to  
move from the ROUND_ACTIVE to the READY  
states.  
Not supported in Fast SupertagMode –  
causes the Transponder to immediately  
switch to ISO Mode.  
BEGIN_ROUND  
Initialises the start of the arbitration sequence  
and tells the Transponder over how many slots  
to randomise the transmit slot selection.  
Configures the transponder to transmit the  
SUID data where DSFID field is replaced by  
AFI field, or the full 128 bit User Data to the  
reader, depending in the SUID parameter in the  
command. Moves the Transponder from the  
READY to the ROUND_ACTIVE states if the  
number of bits of the Transponders User Data  
specified in the command is identical to the  
matching data in the command Mask  
Not supported in Fast SupertagMode –  
causes the Transponder to immediately  
switch to ISO Mode.  
parameter .  
INIT_ROUND_ALL  
Initialises the start of the arbitration sequence  
and tells the Transponder over how many slots  
to randomise the transmit slot selection.  
Not supported in Fast SupertagMode –  
causes the Transponder to immediately  
switch to ISO Mode.  
Configures the Transponder to transmit the  
SUID data or the full 128 bit User Data to the  
Reader dependent on the SUID parameter in  
the command. Moves the Transponder from the  
READY to the ROUND_ACTIVE states.  
NEW_ROUND  
Causes the EM4223 to enter a new Round and  
to change the number of pseudo-slots over  
which it randomises its transmissions. Tags in  
the READY state will ignore this command.  
Causes the EM4223 to change the number of  
pseudo-slots over which it randomises its  
transmissions. Tags in the READY state will  
ignore this command.  
WAKE_UP_FST  
Not supported in ISO Mode – causes the  
Transponder to immediately switch to Fast  
SupertagMode.  
Initialises the start of the Fast Supertagꢀ  
arbitration sequence and tells the  
Transponder over how many slots to  
randomise the transmit slot selection.  
Configures the Transponder to transmit the  
full 128 bit User Data to the Reader  
irrespective of the SUID parameter in the  
command. Moves the Tag from the  
ROUND_STANDBY to the ROUND_ACTIVE  
states or from the READY to the  
ROUND_ACTIVE states if the Mask  
parameter matches, else moves Tag to the  
READY state.
