Tape Mode using the Non-Auto Rewind Option of playback

The following fig. showed a typical playback circuit for non-auto rewind mode. We add a

slide-switch between /REC pin and VSS, and add 3 tact-switches /M0_Tg, /M1_Next,

/M2_CE pin and VSS. When the slide-switch fixed in float side and press /M0_Tg tact-switch ,

chip will start message playback.

Note: After reset, /REC and /M0_Tg, /M1_Next, /M2_/CE and /M7_Option pin will be

pull-up to VDD by internal resistor.

On power-up, beep twice and the device will be ready to play from the first address of

memory array. Send a falling edge to /M0_Tg pin then it will play from the first message &

beep once. During the playback, if /M0_Tg pin receive the falling edge then it will stop

playback immediately. After stop playing, send a falling edge to /M0_Tg pin and it will play

the message from the beginning. If you keep /M0_Tg pin in low potential, this message will

loop playing. Send a falling edge to /M2_CE pin, beep once & go back to the first message to

wait for the next command.

Please note the mode only can play the present message. If you want to hear the next

message, you have to send a falling edge to /M1_Next pin to complete ( beep once ). When

arrive to the end of memory, sending a falling edge to /M0_Tg pin again, the device will beep

twice and go back to the first message to wait for a new command.
