The rising time and falling time of the reception signals (mainly CT103) have to

be less than 200 ns.

The Q24x6 Series have been designed to be operated using all the serial

interface signals. In particular, it is necessary to use RTS and CTS for hardware

flow control in order to avoid data corruption during transmission.
