To repeat playback of the same phrase, keep on inputting “H” level to the PLAY1 or PLAY2
pin. “H” level input to the PLAY1 or PLAY2 causes the LSI to power up and start playback.
The LSI automatically restarts playback when the last address of the phrase has been
reached.
When the playback reaches to the last address of the phrase, with the PLAY1 or PLAY2 pin
being held “L” level, the LSI automatically ends playback.

The LSI automatically powers down after playback ends.
To stop playback before repetitive playback session ends, bring the PLAY1 or PLAY2 pin
down to “L” level once, and then re-input a “H” pulse to the PLAY1 or PLAY2 pin. The LSI
automatically shifts to low-power consumption mode after playback stops.
