Detailed Description

Macro Definition Documentation

NRFX_ASSERT

#define NRFX_ASSERT

(

expression

)

Macro for placing a runtime assertion.

Parameters

expression

Expression to evaluate.

Definition at line 76 of file nrfx_glue.h.

NRFX_ATOMIC_FETCH_AND

#define NRFX_ATOMIC_FETCH_AND	(		p_data,
			value )   nrfx_atomic_u32_fetch_and(p_data, value)

Macro for running a bitwise AND operation on an atomic object and returning its previous value.

Parameters

[in]	p_data	Atomic memory pointer.
[in]	value	Value of the second operand in the AND operation.

Returns

Previous value of the atomic object.

Definition at line 205 of file nrfx_glue.h.

NRFX_CRITICAL_SECTION_ENTER

#define NRFX_CRITICAL_SECTION_ENTER

(

)

{ uint32_t _nrfx_pm = __get_PRIMASK(); __disable_irq()

Macro for entering into a critical section.

Uses PRIMASK save/restore to support proper nesting. The original __disable_irq()/__enable_irq() pair was non-nesting: EXIT would unconditionally re-enable interrupts even if the caller had already disabled them, breaking e.g. the nrf_802154 radio driver's own critical sections.

Definition at line 168 of file nrfx_glue.h.

NRFX_CTZ

#define NRFX_CTZ

(

value

)

__builtin_ctz(value)

Macro for counting trailing zeros.

Parameters

[in]

value

A word value.

Returns

Number of trailing 0-bits in value, starting at the least significant bit position. If x is 0, the result is undefined.

Definition at line 185 of file nrfx_glue.h.

NRFX_IRQ_DISABLE

NRFX_IRQ_ENABLE

#define NRFX_IRQ_ENABLE

(

irq_number
