2.3 Erasing the Phrase 2
(1) While inputting “H” level to the ERASE pin, input “H” pulses to the REC1 and REC2 pins
simultaneously to start erasing the phrase.
(2) After the phrase 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 by recording “Silence” from the top address as far as 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.
