When bit 7 is set to the value of 1, the FOOTPRINT option comes
into use. This option allows some of the commands to leave the

used before bursting into the air. The Reader uses this flag
to decide whether it is required or not.
CRNC=0 determines the regular mode: no carrier sense.
CRNC=1 determines the Reader's ability to sense the carrier.
The Reader executes the RF command only after determining
that the air is free.
