requires SOF; a datastream starting without SOF is ignored
accepts a datastream starting with or without SOF; an SOF is
removed and not written into the FIFO
requires EOF; a datastream ending without EOF generates a
protocol error
accepts a datastream ending with or without EOF; an EOF is
removed and not written into the FIFO
reserved for future use
SOF and EOF have the maximum length defined in
ISO/IEC 14443 B
SOF and EOF have the minimum length defined in
