Instructions:

1. Powering the Device: Connect the VDD pin to a power supply within the specified voltage range (2.4V to 3.6V). Ensure GND is properly grounded.
2. Recording Audio: Use the RECORD command via the SPI interface to start recording. The device will record up to its maximum time limit (16 seconds) or until STOP is issued.
3. Playing Back Audio: Initiate playback using the PLAY command through the SPI interface. Playback continues until the end of the recorded message or until STOP is sent.
4. PWM Output Configuration: Configure the PWM output for appropriate audio amplification or connect directly to a speaker as per application requirements.
5. Entering Shutdown Mode: Send the SHUTDOWN command to enter low-power mode. This reduces current draw to less than 1 μA.
6. Recovering from Shutdown: Send any command to wake the device from shutdown mode and return it to operational status.
7. Handling Multiple Segments: The ISD9160FI supports multiple segments of recordings. Manage these using address pointers and segment control commands.
8. Error Handling: Monitor error flags returned by the device to ensure proper operation and take corrective actions if necessary.
