The MUON command is a 2-byte command.

This command is used to insert silence between the two playback

phrases.

The MUON command is enabled when the NCR signal is at a “H” level.

Set the silence time length

using the second byte of this command.

As the silence length (M7 to M0), a value between 4 ms and 1024 ms can be set in 4 ms intervals (252 steps in

total).

The equation to set the silence time length is shown below.

The silence length (M7-M0) must be set to 04h or higher.

The timing diagram shown below is a case of inserting a silence of 20 ms between the repetitions of a phrase of

to be finished

When the PLAY command is input, the address control of phrase 1 ends, the phrase playback starts, and the

NCR signal goes “H” level.

Input the MUON command after this NCR signal changes to the “H” level.

After

the MUON command input, the NCR signal remains “L” up to the end of phrase 1 playback, and the device

enters a state waiting for the phrase 1 playback to end.

When the phrase 1 playback finishes, the silence playback starts, and NCR1 signal goes “H” level.

After this

NCR signal has changed to the “H” level, re-input the PLAY command in order to play phrase 1.

After the PLAY command input, the NCR signal once again returns to “L” level and the device enters the state

waiting for the end of silence playback.

When the silence playback finishes and then the phrase 1 playback starts, the NCR signal goes “H”, and the

device enters a state in which it is possible to input the next PLAY or MUON command.

The

BUSY signal remains “L” until the end of a series of playback.
