Playback start timing by START command
When the START command is input, the address data of the phrase to be played after the command processing time (t
CB2
) is
read from the flash memory. When the phrase address data is read, the specified phrase starts playback, and when playback is
completed, the BUSYB signal of the playback channel becomes "H" level.
The NCR signal goes to the "L" level during playback preparation, and goes to the "H" level when playback preparation is
completed and playback starts. When the NCR signal of the playback channel becomes "H" level, the START command of
the next phrase to be played can be accepted.
*1 The length of the "L" interval in the BUSYBn is (tCB2+ sound production time).
