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.
