CH0

The STOP command is used to stop playback.

It can be set for each channel.

Setting any bit(s) from CH0 to

CH3 to “1” stops playback on the corresponding channel(s).

If the speech synthesis processing for all channels

stops, the AOUT output goes to the VSG level and the NCR and BUSYB signals go to a “H” level.

Although it is possible to input the STOP command regardless of the status of NCR during playback, a

prescribed command interval time needs taking.
