説明

NDS hardware definitions.

These definitions are usually only touched during the initialization of the program.

---

マクロ定義

#define HALT_CR   (*(vu16*)0x04000300)

Halt control register.

Writing 0x40 to HALT_CR activates GBA mode. HALT_CR can only be accessed via the BIOS.

#define REG_POWERCNT   *(vu16*)0x4000304

Power control register.

This register controls what hardware should be turned on or off.

---

列挙型

enum BACKLIGHT_LEVELS

Backlight level settings.

Note, these are only available on DS Lite.

enum DISP_BITS

LCD Status register bitdefines.

列挙型の値:

DISP_IN_HBLANK	The display currently in a vertical blank.
DISP_YTRIGGERED	The display currently in a horizontal blank.
DISP_VBLANK_IRQ	Current scanline and DISP_Y match.
DISP_HBLANK_IRQ	Interrupt on vertical blank.
DISP_YTRIGGER_IRQ	Interrupt on horizontal blank.

enum PM_Bits

Power Management control bits.

列挙型の値:

PM_SOUND_AMP	Power the sound hardware (needed to hear stuff in GBA mode too).
PM_SOUND_MUTE	Mute the main speakers, headphone output will still work.
PM_BACKLIGHT_BOTTOM	Enable the top backlight if set.
PM_BACKLIGHT_TOP	Enable the bottom backlight if set.
PM_SYSTEM_PWR	Turn the power *off* if set.
POWER_LCD	Controls the power for both LCD screens.
POWER_2D_A	Controls the power for the main 2D core.
POWER_MATRIX	Controls the power for the 3D matrix.
POWER_3D_CORE	Controls the power for the main 3D core.
POWER_2D_B	Controls the power for the sub 2D core.
POWER_SWAP_LCDS	Controls which screen should use the main core.
POWER_ALL_2D	power just 2D hardware
POWER_ALL	power everything
