44KPAD library uses the autosampling from the WPAD library. This function gets the starting address of the <a href="../wpad/WPADStatus.html"><code>WPADStatus</code></a> structure ring buffer used by that autosampling. The length of the buffer is defined in <code>KPAD_RING_BUFS</code>. To reference values in a <a href="../wpad/WPADStatus.html"><code>WPADStatus</code></a> structure directly, use the <a href="../wpad/WPADGetLatestIndexInBuf.html"><code>WPADGetLatestIndexInBuf</code></a> function in parallel to reference the appropriate value.
