Examples of commands
Comments
02021200 – TAG/Card emulation
ISO/IEC14443A,
106kbps
for
transmission & reception, return error if no
HF field detected, HFO used as master
clock
0202120A – TAG/Card emulation
ISO/IEC14443A,
106kbps
for
transmission & reception, wait for HF field,
CLKREC use as master clock
02021300 – TAG/Card emulation
ISO/IEC14443B,
106kbps
for
transmission & reception, return error if no
HF field detected, HFO use as master
clock, CRC automatically added
0202130A – TAG/Card emulation
ISO/IEC14443B,
106kbps
for
transmission & reception, wait for HF field,
CLKREC use as master clock, CRC
automatically added
02021400 – TAG/Card emulation
ISO/IEC18092, return error if no HF field
detected, HFO use as master clock, CRC
automatically added
Note that it is not necessary to select a
data-rate for ISO18092card mode, Data-
rate will be automatically detected and
adjusted during reception (application can
read this information by sending
“SubfreqRecv” command).
