RECORD MESSAGE
During the /REC pin drove to VIL, chip in the record mode.
When the message pin (M0, M1, M2 … M7) drove to VIL in record mode, the chip will playback
“beep” tone and message record starting.
The message record will continue until message pin released or full of this message, and the chip
will playback “beep” tone 2 times to indicate the message record finished.
If the message already exist and user record again, the old one’s message will be replaced.
The following fig. showed a typical record circuit for 8-message mode. We connected a slide-switch
between /REC pin and VSS, and connected 8 tact-switches between M0 ~ M7 pin and VSS. When
the slide-switch fixed in VSS side and any tact-switch will be pressed, chip will start message record
and until the user releases the tact-switch.
Note: After reset, /REC and M0 to M7 pin will be pull-up to VDD by internal resistor.
