We recommend powering up the microphone in Normal mode (mode pin low), and

then entering Wake on Sound mode as needed.

System Architecture

Control loop for Wake on Sound:

Figure 6 above shows a full-featured system built around the VM1010. The VM1010

wakes up the system when triggered by sound. The DSP or voice processor can be

kept in a low-power state when there is no sound to process.
