Audio routing to the Voice Storage circuitry during receive message recording, message playback,
personal memo recording and voice prompt transmit over the air are as follows:
Received Message Recording
The receive audio is tapped from the Rx_Aud_Rtn pin of the ASFIC_CMP during receive mode.
Message Playback
Message playback is via the FLAT_RX_SND pin of ASFIC_CMP. In the ASFIC_CMP, the signal is
routed via the Side-Tone path to the Receive path where playback audio is routed to the speaker.
Personal Memo Recording
In this mode, voice is pick-up at the Mic. and via the Side-Tone path will be directed to the
Rx_Aud_Rtn pin, which is then routed to the voice recording chip.
Voice Prompt transmit over the air
A personal voice prompt or Out-Of-Office Message which is stored in the IC can be transmitted over
the air through mic path in the ASFIC_CMP to the calling party. This feature is similar to the
Telephone Answering Machine feature when the person called is not available to attend the call.
