(4) Communication (transmit/receive) using an asynchronous serial I/O (UART)
Point : 2-byte data is transmitted and received through an asynchronous serial I/O.
The port P40 is used for communication control.
Figure 2.3.29 shows a connection diagram, and Figure 2.3.30 shows a timing chart.
Fig. 2.3.29 Connection diagram [Communication using UART]
Specifications : The Serial I/O is used (UART is selected).
Transfer bit rate : 9600 bps (f(XIN) = 4.9152 MHz is divided by 512)
Communication control using port P40
(The output level of the port P40 is controlled by softoware.)
2-byte data is transferred from the transmitting side to the receiving side at inter-
vals of 10 ms (generated by timer).
