Playback start timing by MUON command
When the first byte of the MUON command is input, the device waits for the input of the second byte after the command
processing time (t
CB1
). When the second byte is entered, the silence time is calculated after the command processing time
(t
CB2
). When the calculation of the silence duration is completed, the calculated silence is played back, and when the
playback is completed, the BUSYB signals of the playback channels become "H" level.
The NCR signal becomes "L" level during playback preparation, and becomes "H" level when playback preparation is
completed and playback starts. When the NCR signal of the playback channel becomes "H" level, the PLAY command of the
next phrase to be played can be accepted.
*1 The length of the "L" interval of the BUSYBn is (tCB2+ silence playback time).
