8.4 Clock asynchronous serial I/O (UART) mode

8.4.2 Transfer data format

The transfer data format can be selected from three formats shown in Figure 8.4.1. By setting bits 6 to 4

at addresses 3016, 3816 and 6416, the transfer data format can be selected. (Refer to Figures 8.2.2 and

8.2.3.) Be sure to set the same transfer data format for both transmitter and receiver sides.

Figure 8.4.2 shows an example of transfer data format. Table 8.4.6 lists each bit in transmit data.
