Atomic modification
These macros are used for atomic access, such as read-modify-write to the peripheral registers. Take SDK_ATOMIC_LOCAL_CLEAR_AND_SET as an example: the parameter `addr` means the address of the peripheral register or variable you want to modify atomically, the parameter `clearBits` is the bits to clear, the parameter `setBits` it the bits to set. For example, to set a 32-bit register bit1:bit0 to 0b10, use like this: volatile uint32_t * reg = (volatile uint32_t *)REG_ADDR; SDK_ATOMIC_LOCAL_CLEAR_AND_SET(reg, 0x03, 0x02); In this example, the register bit1:bit0 are cleared and bit1 is set, as a result, register bit1:bit0 = 0b10. Note For the platforms don't support exclusive load and store, these macros disable the global interrupt to pretect the modification. These macros only guarantee the local processor atomic operations. For the multi-processor devices, use hardware semaphore such as SEMA42 to guarantee exclusive access if necessary.
#define	SDK_ATOMIC_LOCAL_ADD(addr, val)
	Add value val from the variable at address address.

#define	SDK_ATOMIC_LOCAL_SUB(addr, val)
	Subtract value val to the variable at address address.

#define	SDK_ATOMIC_LOCAL_SET(addr, bits)
	Set the bits specifiled by bits to the variable at address address.

#define	SDK_ATOMIC_LOCAL_CLEAR(addr, bits)
	Clear the bits specifiled by bits to the variable at address address.

#define	SDK_ATOMIC_LOCAL_TOGGLE(addr, bits)
	Toggle the bits specifiled by bits to the variable at address address.

#define	SDK_ATOMIC_LOCAL_CLEAR_AND_SET(addr, clearBits, setBits)
	For the variable at address address, clear the bits specifiled by clearBits and set the bits specifiled by setBits.

Timer utilities
#define	USEC_TO_COUNT(us, clockFreqInHz) (uint64_t)(((uint64_t)(us) * (clockFreqInHz)) / 1000000U)
	Macro to convert a microsecond period to raw count value.

Non-cacheable region definition macros
For initialized non-zero non-cacheable variables, please use "AT_NONCACHEABLE_SECTION_INIT(var) ={xx};" or "AT_NONCACHEABLE_SECTION_ALIGN_INIT(var) ={xx};" in your projects to define them. For zero-inited non-cacheable variables, please use "AT_NONCACHEABLE_SECTION(var);" or "AT_NONCACHEABLE_SECTION_ALIGN(var);" to define them, these zero-inited variables will be initialized to zero in system startup. Note For GCC, when the non-cacheable section is required, please define "__STARTUP_INITIALIZE_NONCACHEDATA" in your projects to make sure the non-cacheable section variables will be initialized in system startup.
#define	AT_NONCACHEABLE_SECTION(var) var

Function Documentation

void* SDK_Malloc	(	size_t	size,
		size_t	alignbytes
	)

This is provided to support the dynamically allocated memory used in cache-able region.

Parameters

size	The length required to malloc.
alignbytes	The alignment size.

Return values

The	allocated memory.

void SDK_Free ( void * ptr )

Parameters

ptr	The memory to be release.

void SDK_DelayAtLeastUs	(	uint32_t	delayTime_us,
		uint32_t	coreClock_Hz
	)

Please note that, this API uses while loop for delay, different run-time environments make the time not precise, if precise delay count was needed, please implement a new delay function with hardware timer.

Parameters

delayTime_us	Delay time in unit of microsecond.
coreClock_Hz	Core clock frequency with Hz.

static status_t EnableIRQ ( IRQn_Type interrupt )

inlinestatic

Enable LEVEL1 interrupt. For some devices, there might be multiple interrupt levels. For example, there are NVIC and intmux. Here the interrupts connected to NVIC are the LEVEL1 interrupts, because they are routed to the core directly. The interrupts connected to intmux are the LEVEL2 interrupts, they are routed to NVIC first then routed to core.

This function only enables the LEVEL1 interrupts. The number of LEVEL1 interrupts is indicated by the feature macro FSL_FEATURE_NUMBER_OF_LEVEL1_INT_VECTORS.

Parameters

interrupt The IRQ number.

Return values

kStatus_Success	Interrupt enabled successfully
kStatus_Fail	Failed to enable the interrupt

static status_t DisableIRQ ( IRQn_Type interrupt )

inlinestatic

Disable LEVEL1 interrupt. For some devices, there might be multiple interrupt levels. For example, there are NVIC and intmux. Here the interrupts connected to NVIC are the LEVEL1 interrupts, because they are routed to the core directly. The interrupts connected to intmux are the LEVEL2 interrupts, they are routed to NVIC first then routed to core.

This function only disables the LEVEL1 interrupts. The number of LEVEL1 interrupts is indicated by the feature macro FSL_FEATURE_NUMBER_OF_LEVEL1_INT_VECTORS.

Parameters

interrupt The IRQ number.

Return values

kStatus_Success	Interrupt disabled successfully
kStatus_Fail	Failed to disable the interrupt

static status_t EnableIRQWithPriority	(	IRQn_Type	interrupt,
		uint8_t	priNum

inlinestatic

Only handle LEVEL1 interrupt. For some devices, there might be multiple interrupt levels. For example, there are NVIC and intmux. Here the interrupts connected to NVIC are the LEVEL1 interrupts, because they are routed to the core directly. The interrupts connected to intmux are the LEVEL2 interrupts, they are routed to NVIC first then routed to core.

This function only handles the LEVEL1 interrupts. The number of LEVEL1 interrupts is indicated by the feature macro FSL_FEATURE_NUMBER_OF_LEVEL1_INT_VECTORS.

Parameters

interrupt	The IRQ to Enable.
priNum	Priority number set to interrupt controller register.

Return values

kStatus_Success	Interrupt priority set successfully
kStatus_Fail	Failed to set the interrupt priority.

static status_t IRQ_SetPriority	(	IRQn_Type	interrupt,
		uint8_t	priNum

Return values

kStatus_Success	Interrupt priority set successfully
kStatus_Fail	Failed to set the interrupt priority.

static status_t IRQ_ClearPendingIRQ ( IRQn_Type interrupt )

inlinestatic

Only handle LEVEL1 interrupt. For some devices, there might be multiple interrupt levels. For example, there are NVIC and intmux. Here the interrupts connected to NVIC are the LEVEL1 interrupts, because they are routed to the core directly. The interrupts connected to intmux are the LEVEL2 interrupts, they are routed to NVIC first then routed to core.

This function only handles the LEVEL1 interrupts. The number of LEVEL1 interrupts is indicated by the feature macro FSL_FEATURE_NUMBER_OF_LEVEL1_INT_VECTORS.

Parameters

interrupt The flag which IRQ to clear.

Return values

kStatus_Success	Interrupt priority set successfully
kStatus_Fail	Failed to set the interrupt priority.

static uint32_t DisableGlobalIRQ ( void )

inlinestatic

Disable the global interrupt and return the current primask register. User is required to provided the primask register for the EnableGlobalIRQ().

Returns: Current primask value.

static void EnableGlobalIRQ ( uint32_t primask )

inlinestatic

Set the primask register with the provided primask value but not just enable the primask. The idea is for the convenience of integration of RTOS. some RTOS get its own management mechanism of primask. User is required to use the EnableGlobalIRQ() and DisableGlobalIRQ() in pair.

Parameters

primask value of primask register to be restored. The primask value is supposed to be provided by the DisableGlobalIRQ().

void EnableDeepSleepIRQ ( IRQn_Type interrupt )

Enable the interrupt for wake-up from deep sleep mode. Some interrupts are typically used in sleep mode only and will not occur during deep-sleep mode because relevant clocks are stopped. However, it is possible to enable those clocks (significantly increasing power consumption in the reduced power mode), making these wake-ups possible.

Note: This function also enables the interrupt in the NVIC (EnableIRQ() is called internaly).

Parameters

interrupt The IRQ number.

void DisableDeepSleepIRQ ( IRQn_Type interrupt )

Disable the interrupt for wake-up from deep sleep mode. Some interrupts are typically used in sleep mode only and will not occur during deep-sleep mode because relevant clocks are stopped. However, it is possible to enable those clocks (significantly increasing power consumption in the reduced power mode), making these wake-ups possible.

Note: This function also disables the interrupt in the NVIC (DisableIRQ() is called internaly).

Parameters

interrupt The IRQ number.
