//#define  _DEBUG_DWORD_REPLACE_FLOAT
// ***** Modification history list area ***** //
// Brian1.10, move video to center
// LJY1.10, add CD-G setting
// Micky1.07, remove CHIP_W9928 for 28AF related codes
// Micky0.90, fix the CT908 SP+HL don't match with main video
//  H/W:    if SPVA start line < 4, will pull the whole SPVA down 4 lines.
//          else do nothing.
//  RISC:   if SPVA start line < 4, use Hiword(DRAM_SPVDSHDS)-3 to be real SPVDS value
//          else do nothing.
// LLY0.83b-2, remove the JPEG relative variable and API to HALJPEG.C/ .H
// LLY2.80a, the modification history
//  - porting JPEG relative code for CT908 by CoCo
//  - remove the code while un-define UNRESET_BEFORE_CDROM_DECODING,
//    ie. always go "unreset" path
//  - remove the code while un-define "SUPPORT_48K_DAC",
//    ie. default go "48K DAC" path
//  - remove the code "_WaitCDIFEnd()"

// LLY2.80, the modification history
// [1] Review global variables initial action
// [2] Merge HAL_ZOOM_XXX into VIEW_ZOOM_XXX
// [3] Use mnemonic instead number to specify DM address -- Chuan2.80


// LLY.170, Review the initial action for global variable
// . Remove the initial value if it's necessary
// [1] __bMPEGVideoMode: the value will be given in HAL_TVEncodeInitial() first
// [2] _bSampleFreq: the value will be given in HAL_SetAudioDAC() first
// [3] _bDownSample: the value will be given in _CheckDACAbility() first
// . Remove the initial action for global variable to INITIAL_Variables_PowerON()
// Thue, the code size of commom bank can be reduced
// [1] _wVBICTLR: HAL_VCD30_Area() will refer it, too.
//                And we can't make sure it will be called after HAL_AdjustTVMode()
// [2] _dwFrameRateCTL: HAL_VCD30_Area() will refer it, too.
//                      And we can't make sure it will be called after HAL_AdjustTVMode()
// [3] _bVideoOutput: Will be used to compare with __SetupInfo.bVideoOutput first
//                    Then, decide if call _TVModeSet() -- the value will be given within it



// LLY.105, compatible with W9928AF -- AVIDR index is same as system register

// LLY.103, Something need re-modify
// [1] "_bLBMode==TRUE"     -->         "_bVideoDisplayMode==SETUP_SCREEN_TV_TYPE_LB"
// [2] Avoid "22QF078.DOC: __dwCountSystem accessing trap" problem
//     Using UTL_GetSysTimer() instead of __dwCountSystem

// LLY.102p, some item modification for TVMode integration
// [1] "__bTVMode"          -->         __SetupInfo.bTVSystem
// [2] "TVMODE_PAL"         -->         SETUP_SCREEN_TV_SYSTEM_PAL
// [3] "TVMODE_NTSC"        -->         SETUP_SCREEN_TV_SUSTEM_NTSC
// [4] "TVMODE_PAL_M"       -->         SETUP_SCREEN_TV_SUSTEM_PAL_M
// [3] "TVMODE_PAL_N"       -->         SETUP_SCREEN_TV_SUSTEM_PAL_N
// [4] "__bTVType"          -->         __bMPEGVideoMode  (keep real MPEG video mode)

// LLY.101b, using __bTVType instead of __bTVMode

// LLY.101-2, merge PAL_M/ PAL_N/ PAL

// LLY.099, adjust and give some DRAM variable name
// [1] "W99AV_DRAM_DIGEST_SHOW"     -->     "W99AV_DRAM_DIG_SHOW"
// [2] "W99AV_DRAM_DIGEST_CONT"     -->     "W99AV_DRAM_CONT_DIG_SHOW"
// [3] "W99AV_DRAM_DIGEST_HVSTART"  -->     "W99AV_DRAM_DIG_HVSTART"
// [4] "W99AV_DRAM_DIGEST_SHSV"     -->     "W99AV_DRAM_DIG_SHSV"
// [5] "W99AV_DRAM_STILL"           -->     "W99AV_DRAM_STILL_MODE"
// [6] "W99AV_DRAM_SKIP_VIDEO_DATA" -->     "W99AV_DRAM_SKIP_PIC"
// [7] "W99AV_DRAM_SKIP_B_DATA"     -->     "W99AV_DRAM_IPDECED"
// [8] "W99AV_DRAM_UPDATE_SEQUENCE" -->     "W99AV_DRAM_UPDATE_SEQ"
// [9] "WPXL_COLOR_ADDR"            -->     "W99AV_DRAM_WPXL_YADR"
// [10]"W99AV_DRAM_SP_OFF"          -->     DRAM[0x59]
// [11]"W99AV_DRAM_SP_TOP"          -->     DRAM[0x5e]
// [12]"W99AV_DRAM_SKIP_MOSAIC"     -->     DRAM[0x6d]

// LLY.045-1, porting for new define depending on 22QF055.DOC
// all original include file will be put in "winav.h"

// LLY.045, use new setup info. definition
