As far as I know, the ATR logic (Automatic Transmit Receiver) in the
FPGA *always* switches the
RX-chain away from the TX/RX port when transmitting. What I'm not
sure of is whether sending
zeroes is enough to cause the ATR logic to go into "not transmitting",
or whether you actually
have to interrupt the data flow.
Perhaps Josh can comment?
