车载电子影音系统dvd播放系统原程序代码

// ******  Big modification History Area  ******
// Micky1.21, CodeReview
//  - Remove __btFreeze.
// Micky1.07, remove CHIP_W9928 for 28AF related codes
// Micky1.07, remove DVD28C_xxx reference
// Micky1.07, remove CDDA_WAITSERVO

// LLY.274p, some big modification
// [1] rename all MP3 relative info. because module name has changed !!
//     - "mp3.h"  -->  "fmanager.h"
//     - MP3_GetRange()  -->  FM_GetRange()
// Micky2.80a
//  - remove all COMMAND_AUDIO codes.
//  - remove MULTI_DISC_SYSTEM codes
//  - remove unused codes from UTL_GetCurrentTime(), DiffOfTwo(), UTL_ReadSectors()
// LLY2.80a, the modification history
//  - remove the code while un-define UNRESET_AFTER_CDROM_DECODING,
//    ie. always go "unreset" path
