Description

1st Byte

51h

Use this command to read the Start and End address values of the

specified phrase.

2nd Byte Phrase[7:0]

The value for the Phrase. Range: 01h to FFh

3rd Byte

4th Byte

5th Byte

Stadr[23:16](O)

Stadr[15:8] (O)

Stadr[7:0] (O)

Outputs the Start Address (in serial from the SO pin).

6th Byte

7th Byte

8th Byte

Enadr[23:16](O)

Enadr[15:8](O)

Enadr[7:0](O)

Outputs the End Address (in serial from the SO pin).

Adrrd

This command allows you to read the Start Address and End Address of

the phrase specified.

1st Byte

50h

Use this command to write the Start and End address values of the

specified phrase.

2nd Byte Phrase[7:0]

The value for the Phrase. Range: 01h to FFh

3rd Byte

4th Byte

5th Byte

Stadr[23:16]

Stadr[15:8]

Stadr[7:0]

The value for the Start Address. You need to set the lower 7 bits to “0”.

6th Byte

7th Byte

8th Byte

Enadr[23:16]

Enadr[15:8]

Enadr[7:0]

The value for the End Address. You need to set the lower 7 bits to “1”.

Adrwr

With this command you can define a phrase and the Start and End

addresses of the phrase. Addressing is in Pages. You should specify

the page's top address (the lower 7 bits = 0) for the Start Address, while

the page's end address (the lower 7 bits = 1) for the End Address.

If you specify Stadr = Enadr, the LSI performs endless (loop) recording.

Note: You may not specify the Start address value that is larger than the

End address.

1st Byte

70h

Deletes the specified phrase(s).

2nd Byte Phrase[7:0]

The value for the Phrase. Range: 01h to FFh

Del

If you specify “00h” for the Phrase, all phrase data will be erased.

1st Byte

41h

Pauses recording or playing.

Pause

Re-entering the command resets pause state and resumes the earlier

operation.

Start

2nd Byte Phrase[7:0]

Starts recording or playing.

Stop

1st Byte

40h

Stops recording or playing.
