5 / 20 page OKI ML2502 ML2502 Data Sheet (Revision 8.0) 5 1.2 Phrase 1 Playback Operation (1) Input a “H” pulse to the PLAY1 pin to power up and start playback from the top address of the memory. (2) The LSI automatically ends playback when the last address of the recorded phrase has been reached. (3) The LSI automatically shifts to low-power consumption mode after playback ends. (4) To stop playback of phrase 1 before reaching the last address, input a “H” pulse again to the PLAY1 or PLAY2 pin. This will cause the LSI to stop playback and then automatically shift to low-power consumption mode. (5) During playback operation signal input to the PLAY1 or PLAY2 pin only is valid, any other signal input is disregarded Figure 1.2 Timing Chart for Phrase 1 Playback Operation 1.3 Phrase 1 Erasing Operation (1) While inputting “H” level to the ERASE pin, input a “H” pulse to the REC1 pin to start erasing Phrase 1. (2) After Phrase 1 having been erased, the LSI automatically shifts to power-down mode for low-power consumption. Note: Erasing operation cannot be abandoned in the middle once getting started. Internally, the LSI performs erasing Phrase 1 by recording “Silence” from the top address to address 250. Therefore, if you attempt to playback the erased phrase, the playback starts at the top address of the memory and ends at address 250.
