1.6 Phrase 2 Erasing Operation
(1)
(2)
While inputting “H” level to the ERASE pin, input a “H” pulse to the REC2 pin to start erasing
Phrase 2.
After Phrase 2 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 2 by recording “Silence” from the center
address as far as to address 250. Therefore, if you attempt to playback the erased
phrase, the playback starts at the center address of the memory and ends at address 250.
