#include <nitro/os.h>OSIntrMode OS_EnableInterrupts_IrqAndFiq( void );None.
Returns a value that indicates the state before this function was called.
The return value type is OSIntrMode (a u32 typedef), but the return value is the logical sum of the OSIntrMode_Irq and OSIntrMode_Fiq enumerated types.
The OSIntrMode_Irq enumerated type:
| Value | Previous state |
|---|---|
| OS_INTRMODE_IRQ_DISABLE | IRQ Disable (prohibited) |
| OS_INTRMODE_IRQ_ENABLE | IRQ Enable (permitted) |
The OSIntrMode_Fiq enumerated type:
| Value | Previous state |
|---|---|
| OS_INTRMODE_FIQ_DISABLE | FIQ Disable (prohibited) |
| OS_INTRMODE_FIQ_ENABLE | FIQ Enable (permitted) |
This function enables the IRQ and FIQ interrupts.
The master enable flag for all interrupts (the Interrupt Master Enable Flag) is enabled here. Even if the IRQ interrupt causes are enabled separately, interrupts will not be generated if IRQ is prohibited with this function.
The return value indicates the state prior to calling the function.
The CPSR register (current program status register) IRQ and FIQ interrupt control bits are reset (the reset is enabled).
