Description
identifies the MIFARE DESFire EV1 type to the PCD
allows individual selection of the communication baud rate between PCD and
MIFARE DESFire EV1; for DESFire it is possible to set different
communication baud rates for each direction i.e. DESFire allows a
non-symmetrical information interchange speed.
if the MIFARE DESFire EV1 needs more time than the defined FWT to
respond to a PCD command it requests a Waiting Time eXtension (WTX)
allows MIFARE DESFire EV1 to be brought to the HALT state
