Reading a COTAG.
COTAG needs the reader to send a startsequence and the card has an extreme slow datarate.
because of this, we can "sample" the data signal but we interpreate it to Manchester direct.
READER START SEQUENCE:
burst 800 us, gap 2.2 msecs
burst 3.6 msecs gap 2.2 msecs
burst 800 us gap 2.2 msecs
pulse 3.6 msecs
This triggers a COTAG tag to response
