Function Documentation

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 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 convinience 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().

uint32_t InstallIRQHandler	(	IRQn_Type	irq,
		uint32_t	irqHandler
	)

Parameters

irq	IRQ number
irqHandler	IRQ handler address

Returns: The old IRQ handler address

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 internally).

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 internally).

Parameters

interrupt The IRQ number.

void POWER_WritePmuCtrl1	(	SYSCON_Type *	base,
		uint32_t	mask,
		uint32_t	value
	)

Refer to Errata PMU.1.

void POWER_EnablePD ( pd_bit_t en )

Note that enabling the bit powers down the peripheral

Parameters

en	any value defined by enum

void POWER_DisablePD ( pd_bit_t en )

Note that disabling the bit powers up the peripheral

Parameters

en	any value defined by enum

void POWER_EnableDCDC ( bool flag )

Parameters

flag	true to enable the DC-DC, false to disable.

void POWER_EnableADC ( bool flag )

Parameters

flag	true to enable the ADC power, false to disable.

void POWER_LatchIO ( void )

During power down, GPIO registers at GPIOA_BASE and GPIOB_BASE will get lost, and GPIO controller loses control of the pads. This result in uncetain level on pads during power down. Use this function to capture the current GPIO output status and level to always-on registers, SYSCON->PIO_CAP_OUT0/1 and SYSCON->PIO_CAP_OE0/1, and hand over control of pads to these always-on registers.

void POWER_RestoreIO ( void )

Should be called in pair with POWER_LatchIO().

void POWER_EnableSwdWakeup ( void )

By using this, the chip can be waked up by swd debugger from power down.

void POWER_PreEnterLowPower ( void )

This function should be called before entering low power modes.

void POWER_PostExitLowPower ( void )

This function should be called after wake up from low power modes. It is used with POWER_PreEnterLowPower.

void POWER_EnterPowerDown ( uint32_t exclude_from_pd )

If 32k clock source is on before calling this, the chip will go to power down 0. If 32k clock source is turned off before this, the chip will go to power down 1.

Parameters

exclude_from_pd when entering power down, leave the modules indicated by exclude_from_pd on.

static void RESET_SetPeripheralReset ( reset_ip_name_t peripheral )

inlinestatic

Asserts reset signal to specified peripheral module.

Parameters

peripheral Assert reset to this peripheral. The enum argument contains encoding of reset register and reset bit position in the reset register.

Note: The peripheral will be in reset state until function RESET_ClearPeripheralReset(...) called.

static void RESET_ClearPeripheralReset ( reset_ip_name_t peripheral )

inlinestatic

Clears reset signal to specified peripheral module, allows it to operate.

Parameters

peripheral Clear reset to this peripheral. The enum argument contains encoding of reset register and reset bit position in the reset register.

static void RESET_PeripheralReset ( reset_ip_name_t peripheral )

inlinestatic

Reset peripheral module.

Parameters

peripheral Peripheral to reset. The enum argument contains encoding of reset register and reset bit position in the reset register.

reset_source_t RESET_GetResetSource ( void )

Returns: Reset source reset_source_t
