7.5.8 ISO14443-3 type A card activation commands
ISO14443-3_Request_Wakeup
Issue a request or wake-up command.
ISO14443-3_Anticollision_Select
Perform bit-wise anticollision and select. The anticollision and the following select are
performed according to the select code in the data field.
The selection can be carried out for a variable amount of cascade levels. The select
codes have to be listed in the data field subsequently. The SAM will take the parameters
exactly and use them as select code. Therefore to fully select a card with a triple UID, the
data field has to be of three bytes length indicating 93h, 95h and 97h whereas the data
field has to be of one byte length indicating 93h if a single size UID card is to be selected.
If the select code indicates a cascade level of 93h and 95h, and the UID of the card
consists only of four bytes, the SAM exits the command and returns the SAK and the UID
of the card.
If the select code indicates a cascade level of 93h, and the UID consists of more than four
bytes, the SAM also exits the command and returns the SAK and the first three bytes of
the UID but indicates with a special return code the incompleteness of the UID separately.
The caller has then to take care about continuing the procedure on his own by calling the
command once more with a higher select code. The UID bytes already returned will not be
returned a second time. The same applies for a select code of 95h if the UID is of ten
bytes length (suggest that a selection with code 93h is implemented first).
ISO14443-3_ActivateIdle
Carries out one or several request - anticollision - select sequences and returns the SAK
and the UID of the selected card(s). The ATQA is returned for every request issued, this
means for every newly activated card. Due to the fact that the resulting ATQA is the
OR-function of all ATQAs, the value may change frequently.
ISO14443-3_ActivateWakeup
The command reactivates and selects a card that has previously been set to Halt state.
The command takes the UID of the card to reactivate.
ISO14443-3_HaltA
The command puts a selected card into Halt state.
ISO14443-3_TransparentExchange
Exchange bytes/bits transparently. The SAM takes the user data and sends it without
changing, inserting or appending any content to the contactless card. Appending a CRC,
time-out settings, etc. have to be configured by directly writing to the MFRC52X registers.
Take into account that switching settings of the reader chip influence all subsequent SAM
commands proposing the correct reader chip settings, i.e. ISO14443-4_Exchange.
