Continuous playback timing by MUON command
After the PLAY command is input, the CBUSYB signal and NCR signal change to "H" level when the address management
of phrase 1 is completed and start playing back. Input the MUON command after the CBUSYB signal changed to "H" level.
After the MUON command is received, the LSI is in a state waiting for the end of playback of phrase 1 and the NCR signal
remains "L" level until the end of playback.
When the playback of phrase 1 ends, playback of the silence sound starts and the NCR signal changes to "H" level. After the
NCR signal of the corresponding channel changes to "H" level, send the PLAY command again to playback the phrase 1.
The NCR signal changes to "L" level again after the PLAY command is received and the LSI is in a state waiting for the end
of the playback of silence sound.
After ending the playback of silence sound and starting the playback of phrase 1, the NCR signal changes to "H" level and
LSI is in state that accepts the next PLAY or MUON command.
The BUSYB signal remains "L" level until the sequence of playback is completed.
When making continuous playbacks, input the MUON/PLAY/START command for the next phrases within 10ms (t
cm
) after
the NCR of the corresponding channel changes to "H" level.
