MSM665x Reaet. This pin provides a reset signal for an external speech
synthesis engine.
MSM665x Strobe. This output provides the LOAD signal for an external
speech synthesizer.
MSM665x Busy. When using an external MSM665x device, this pin monitors
the MSM665x BUSY signal and connects directly to the MSM665x BUSY
signal output.
MSM665x Serial Clock. This MSM6679AL-110 output connects to the
MSM665x SI input. The SI pin is the MSM665x serial clock input pin.
MSM665x Serial Data. This MSM6679AL-110 output connects to the
MSM665x SD input. The SD pin is the MSM665x serial data input pin.
Voice Out. This pin is the PWM output for speech synthesis, voice sample
playback, and voice prompts. An external integrator must be used to convert
this to an analog signal.
MSM665x Next Address Request. This pin signals to the MSM6679AL-110
that the external speech synthesis engine is ready for another command.
Reserved. These pins are reserved for future use and must be tied to VDD.
Reserved. This pin is reserved for future use and must be tied to VDD.
Power down release. Power down mode is released by both edge of PDC
signal.
