3. Repeating Playback Operation

ML2502

(1) 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.

(2) The LSI automatically restarts playback when the last address of the phrase has been

reached.

(3) 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.

(4) The LSI automatically powers down after playback ends.

(5) 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.
