PLAYBACK MESSAGE
During the /REC pin drove to VIH, chip in the playback mode.
When the message pin (M0, M1, M2 … M7) drove from VIH to VIL in playback mode, the message
playback starting.
The message playback will continue until message pin drove from VIH to VIL again or end of this
message.
The following fig. showed a typical playback circuit for 8-message mode. We connected a
slide-switch between /REC and VSS, and connected 8 tact-switches between M0 ~ M7 and VSS.
When the slide-switch fixed in float side and any tact-switch will be pressed, chip will start message
playback and until the user pressed the tact-switch again or end of message.
Note: After reset, /REC and M0 to M7 pin will be pull-up to VDD by internal resistor.
