9. CLOOP Command
The CLOOP command releases the repetitive playback.
When the repetitive playback mode is released, the NCR goes to the “H” level.
It is possible to input the CLOOP command regardless of the status of the NCR of that is playing back, but the
prescribed command interval is required.
CLOOP Command Input Timing
Depending on the timing of the CLOOP command input during repetitive playback, the repetitive playback will end
either at the end of the currently playing back phrase or after one more repetition of the phrase.
The difference is due to the same process that is required for repetitive playback and normal continuous playback. If
the CLOOP command is input at a point in the phrase where the remaining voice data is less than the number of
sampling periods required for address management, the address management of the next phrase to be played back (in
this case, the same phrase) will have already begun. As the conclusion of address management automatically starts
the next phrase playback, the CLOOP command will not take effect until that repetition is complete.
The input timing of the CLOOP command that is necessary to release repetitive playback without the final repetition
is the same as the input timing for the PLAY command in which no silence is inserted between the phrases at the
time of continuous playback, as shown in the table below.
If the CLOOP command for the second phrase is input before the number of samples indicated in the table is reached,
repetitive playback ends at the end of the currently playing back phrase.
