RTS/CTS Option 1: If you select RTS/CTS Option 1, the device asserts RTS before transmitting and ignores
the state of CTS. The device de-asserts RTS when the transmission completes.

•
RTS/CTS Option 2: If you select Option 2, RTS is always high or low (user-programmed logic level).
However, the device waits for CTS to be asserted before transmitting data. If CTS is not asserted within Host
Serial Response Time-out (default), the device issues an error indication and discards the data.

RTS/CTS Option 3: If you select Option 3, the device asserts RTS prior to any data transmission, regardless
of the state of CTS. The device waits up to Host Serial Response Time-out (default) for CTS to be asserted.
