Figure 1–3. Byte Mode

The word or byte mode is selected by first connecting the DATA-DR/CONTROL input to VCC–.

FSD/WORD-BYTE becomes an input and can then be used to select either word or byte transmission

formats. The end-of-data transmit (EODX) and the end-of-data receive (EODR) signals respectively, are

used to signal the end of word or byte communication (see the Terminal Functions section).
