OSIrqMask OS_GetIrqMask( void );
None.
The setting for the current IRQ interrupt cause.
Obtains the setting for the currently established IRQ interrupt cause
The returned value is the logical sum whose value corresponds to the interrupt cause from the table below.
OS_IE_V_BLANK | V-blank interrupt |
OS_IE_H_BLANK | H-blank interrupt |
OS_IE_V_COUNT | V counter interrupt |
OS_IE_TIMER0 | Timer0 interrupt |
OS_IE_TIMER1 | Timer1 interrupt |
OS_IE_TIMER2 | Timer2 interrupt |
OS_IE_TIMER3 | Timer3 interrupt |
OS_IE_DMA0 | DMA0 interrupt |
OS_IE_DMA1 | DMA1 interrupt |
OS_IE_DMA2 | DMA2 interrupt |
OS_IE_DMA3 | DMA3 interrupt |
OS_IE_KEY | Key interrupt *1 |
OS_IE_CARTRIDGE | Game Pak IREQ/DREQ interrupt |
OS_IE_SUBP | ARM7 interrupt |
OS_IE_SPFIFO_SEND | ARM9-ARM7 send FIFO empty interrupt |
OS_IE_SPFIFO_RECV | ARM9-ARM7 receive FIFO not-empty interrupt |
OS_IE_CARD_DATA | Card data transfer end interrupt |
OS_IE_CARD_IREQ | Card IREQ interrupt |
OS_IE_GXFIFO | Geometry command FIFO interrupt |
*1 The hardware specification does not allow the use of the key interrupt. However, it can be used for waking from sleep.
Reads IE (Interrupt Enable) of the IO register and returns that value.
