// FUNCTION  : MDD-PDD interface layer of waveform audio driver
// HISTORY   : 
//             2003.06.20
//              - Created release code.
//                (based on WaveDev driver for ITS-DS6 Ver.2.2.0 for WCE4.1)
//             2004.09.01
//              - Created release code for WCE5.0.
//             2005.04.26
//              - Modified PCM data size from 20bit to 16bit Packed RX DMA.
