6. STOP Command
STOP command is used to stop playback. When the speech synthesis processing stops, the AOUT output of that
channel becomes 1/4V
Although it is possible to input the STOP command regardless of the status of playing back NCR, a prescribed
command interval time is necessary.
Note that STOP command input during power down, shifting to power up, and shifting to power down will be
ignored.
If the STOP command input is carried out, an AOUT output will change to the level of about 1 V. For this reason, a
pop noise may be generated. Input the STOP command to prevent a pop noise after making volume small gradually
using the VOL command.
