Macros
#define	RTEMS_ALL_MODE_MASKS   0x0000ffff
	This task mode constant is a bit mask with all mode bits set.
#define	RTEMS_ASR   0x00000000
	This task mode constant indicates that signal processing is disabled.
#define	RTEMS_ASR_MASK   0x00000400
	This mode constant corresponds to the signal enable/disable bit.
#define	RTEMS_CURRENT_MODE   0
	This task mode constant indicates that the current task mode of the executing task shall be returned by rtems_task_mode().
#define	RTEMS_DEFAULT_MODES   0x00000000
	This task mode constant represents the default mode set.
#define	RTEMS_INTERRUPT_MASK   CPU_MODES_INTERRUPT_MASK
	This task mode constant corresponds to the interrupt enable/disable bits.
#define	RTEMS_INTERRUPT_LEVEL(_interrupt_level)    ( ( _interrupt_level ) & RTEMS_INTERRUPT_MASK )
	Maps the interrupt level to the associated processor-dependent task mode interrupt level.
#define	RTEMS_NO_ASR   0x00000400
	This task mode constant indicates that signal processing is disabled.
#define	RTEMS_NO_PREEMPT   0x00000100
	This task mode constant indicates that preemption is disabled.
#define	RTEMS_NO_TIMESLICE   0x00000000
	This task mode constant indicates that timeslicing is disabled.
#define	RTEMS_PREEMPT   0x00000000
	This task mode constant indicates that preemption is enabled.
#define	RTEMS_PREEMPT_MASK   0x00000100
	This task mode constant corresponds to the preemption enable/disable bit.
#define	RTEMS_TIMESLICE   0x00000200
	This task mode constant indicates that timeslicing is enabled.
#define	RTEMS_TIMESLICE_MASK   0x00000200
	This task mode constant corresponds to the timeslice enable/disable bit.

Typedefs
typedef uint32_t	rtems_mode
	This type represents a Classic API task mode set.

Functions
rtems_mode	rtems_interrupt_level_body (uint32_t level)
	Maps the interrupt level to the associated processor-dependent task mode interrupt level.

Variables
const uint32_t	rtems_interrupt_mask
	This task mode constant has the same value as RTEMS_INTERRUPT_MASK.
