31<p>The PMIC library maintains a buffer to hold the reference data to send to the Wii Speak. The buffer is large enough to hold 48 milliseconds of reference data for a sampling frequency of 16,000 Hz.</p>
32
33<p><B>Note: The size of the reference data buffer is fixed regardless of the method used to initialize the PMIC library.</B></p>
34
35<p>This function is used to check if data was overwritten in this internal buffer.</p>
36
37<p>This function can be called regardless of the state of the Wii Speak (such as before it is open or while it is stopped or operating). </p>
