Function Documentation

void clear_irq_funcs (    )

Clears associated functions of all interrupts.

void irq_init (    )

Clears all interrupts and sets the master interrupt handling function. This must be called before using any interrupt functions.

void set_irq_func (  u8    type, void(*    func)() )

Parameters: type  [IRQ] Interrupt Type func  Pointer to function Associates a function with an interrupt type. Interrupt Type defines: */ #define IRQ_VBL #define IRQ_HBL #define IRQ_VCOUNT #define IRQ_TIM0 #define IRQ_TIM1 #define IRQ_TIM2 #define IRQ_TIM3 #define IRQ_COMM #define IRQ_DMA0 #define IRQ_DMA1 #define IRQ_DMA2 #define IRQ_DMA3 #define IRQ_KEY #define IRQ_CART

void set_irq_mode (  u8    type, bool    enable )

Parameters: type  [IRQ] Interrupt Type enable  [TRUE or FALSE] Enable Interrupt Enable or disable the interrupt. Make sure to use set_irq_func() first. Interrupt Type defines: */ #define IRQ_VBL #define IRQ_HBL #define IRQ_VCOUNT #define IRQ_TIM0 #define IRQ_TIM1 #define IRQ_TIM2 #define IRQ_TIM3 #define IRQ_COMM #define IRQ_DMA0 #define IRQ_DMA1 #define IRQ_DMA2 #define IRQ_DMA3 #define IRQ_KEY #define IRQ_CART

void irq_start (  u8    type )

Parameters: type  [IRQ] Interrupt Type Enable the interrupt. Make sure to use set_irq_func() first. Interrupt Type defines: */ #define IRQ_VBL #define IRQ_HBL #define IRQ_VCOUNT #define IRQ_TIM0 #define IRQ_TIM1 #define IRQ_TIM2 #define IRQ_TIM3 #define IRQ_COMM #define IRQ_DMA0 #define IRQ_DMA1 #define IRQ_DMA2 #define IRQ_DMA3 #define IRQ_KEY #define IRQ_CART

void irq_stop (  u8    type )

Parameters: type  [IRQ] Interrupt Type Disable the interrupt. Interrupt Type defines: */ #define IRQ_VBL #define IRQ_HBL #define IRQ_VCOUNT #define IRQ_TIM0 #define IRQ_TIM1 #define IRQ_TIM2 #define IRQ_TIM3 #define IRQ_COMM #define IRQ_DMA0 #define IRQ_DMA1 #define IRQ_DMA2 #define IRQ_DMA3 #define IRQ_KEY #define IRQ_CART
