Prior to starting a data transmission or reception, the A must be loaded with a set of control words generated by the microprocessor. These control signals define the complete functional definition of the A and must immediately follow a reset operation internal or external.

The control words are split into two formats. Mode instruction is used for setting the function of the A.

Mode instruction will be in “wait for write” at either internal reset or external reset. That is, the writing of a control word after resetting will be recognized as a “mode instruction.

The bit configuration of mode instruction format is shown in Figures below. In the case of synchronous mode, it is necessary to write one-or two byte sync characters.

If sync characters were written, a function will be set because the writing of sync characters constitutes part of. Command is used for setting the operation of the It is possible to write a command whenever necessary after writing a mode instruction and sync characters. It is possible to see the internal status of the by reading a status word. The format of status word is shown below.
