#include <nitro/os.h>
OSIntrMode OS_RestoreInterrupts_IrqAndFiq( OSIntrMode state );
state | Interrupt status set up (OSIntrMode itself is a u32 typedef) |
The state before the function is called. This is the logical sum of OSIntrMode_Irq
enum value and OSIntrMode_Fiq
enum value.
OS_INTRMODE_IRQ_DISABLE | IRQ Disable (prohibited) |
OS_INTRMODE_IRQ_ENABLE | IRQ Enable (permitted) |
Returns the OSIntrMode_Fiq
enum value:
OS_INTRMODE_FIQ_DISABLE | FIQ Disable (prohibited) |
OS_INTRMODE_FIQ_ENABLE | FIQ Enable (permitted) |
This function sets the interrupt state. It takes the interrupt state given by the argument. The status is provided by the logical sum of the IRQ status expressed in OSIntrMode_Irq
enumerated, and the FIQ status expressed in OSIntrMode_Fiq
enumerated. Mainly the return values are from OS_EnableInterrupts_IrqAndFiq()
and OS_DisableInterrupts_IrqAndFiq()
.
They are most likely useful for returning to the previous status.
The CPSR register (current program status register) IRQ and FIQ interrupt control bits are set/reset.
OS_EnableInterrupts_IrqAndFiq, OS_DisableInterrupts_IrqAndFiq, OS_RestoreInterrupts
