Communication (transmission/reception) using asynchronous serial I/O (UART)

Outline : 2-byte data is transmitted and received, using the asynchronous serial I/O.

Port P56 is used for communication control.

Figure 2.3.50 shows a connection diagram, and Figure 2.3.51 shows a timing chart.

Specifications : • Use of serial I/O2 in UART

• Transfer bit rate : 9600 bps (f(XIN) = 3.6864 MHz is divided by 384)

• Data format : 1ST-8DADA-2ST

• Communication control using port P56

(The output level of port P56 is controlled by softoware.)

• 2-byte data is transferred from the transmission side to the receiption side at

intervals of 10 ms generated by the timer.
