Clock-Synchronous Serial I/OMitsubishi microcomputers<strong>M16C</strong> / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTER2.4.5 Precautions for Serial I/O (in clock-synchronous serial I/O)Transmission/reception_______________(1) With an external clock selected, and choosing the RTS function, the output level of the RTSipin goes to “L” when the data-receivable status becomes ready, which informs the transmis-________sion side that the reception has become ready. The output level of the RTSi pin goes to “H”________________when reception starts. So if the RTSi pin is connected to the CTSi pin on the transmissionside, the circuit can transmission and reception data with consistent timing. With the internal_______clock, the RTS function has no effect. Figure 2.4.16 shows an example of wiring.Transmitter side ICTxDiReceiver side ICTxDiRxDiRxDiCLKiCTSiCLKiRTSiFigure 2.4.16.
