The MSM665x interface consists of the following signals:
• BUSY - Asserted LOW during MSM665x device playback. The MSM6679AL-110 F50Bh and
• NAR - Next Address Request status signal. By default, the MSM6679AL-110 uses this signal
• SI - Serial Input Clock.
• SD - Serial Data Out.
• STROBE - Initiates speech synthesis.
• RESOUT - Initializes device when asserted LOW. The MSM6679AL-110 F480h command
Serial Interface
The MSM6679AL-110 supplies a serial interface suitable for connection to an RS-232C serial port
buffer or equivalent. The serial interface uses one MSM6679AL-110 input (RXD) and one
MSM6679AL-110 output (TXD). The interface operates at 9600 Baud with:
• 8 data bits
• 1 start bit
• 1 stop bit
• No parity
• No handshake
A host processor sends serial ASCII commands to the MSM6679AL-110 and receives serial ASCII
responses based on voice input responses.

generates this signal.
Longer speech patterns can be created by chaining and repeating existing speech samples.
Via external ROM only (no on-chip ROM available).
