Function Documentation

void PMC_ConfigureLowVoltDetect	(	PMC_Type *	base,
		const pmc_low_volt_detect_config_t *	config
	)

This function configures the low-voltage detect setting, including the trip point voltage setting, enables or disables the interrupt, enables or disables the system reset.

Parameters

base	PMC peripheral base address.
config	Low-voltage detect configuration structure.

static bool PMC_GetLowVoltDetectFlag ( PMC_Type * base )

inlinestatic

This function reads the current LVDF status. If it returns 1, a low-voltage event is detected.

Parameters

base	PMC peripheral base address.

Returns

Current low-voltage detect flag

true: Low-voltage detected
false: Low-voltage not detected

static void PMC_ClearLowVoltDetectFlag ( PMC_Type * base )

inlinestatic

This function acknowledges the low-voltage detection errors (write 1 to clear LVDF).

Parameters

base	PMC peripheral base address.

void PMC_ConfigureLowVoltWarning	(	PMC_Type *	base,
		const pmc_low_volt_warning_config_t *	config
	)

This function configures the low-voltage warning setting, including the trip point voltage setting and enabling or disabling the interrupt.

Parameters

base	PMC peripheral base address.
config	Low-voltage warning configuration structure.

static bool PMC_GetLowVoltWarningFlag ( PMC_Type * base )

inlinestatic

This function polls the current LVWF status. When 1 is returned, it indicates a low-voltage warning event. LVWF is set when V Supply transitions below the trip point or after reset and V Supply is already below the V LVW.

Parameters

base	PMC peripheral base address.

Returns

Current LVWF status

true: Low-voltage Warning Flag is set.
false: the Low-voltage Warning does not happen.

static void PMC_ClearLowVoltWarningFlag ( PMC_Type * base )

inlinestatic

This function acknowledges the low voltage warning errors (write 1 to clear LVWF).

Parameters

base	PMC peripheral base address.

void PMC_ConfigureBandgapBuffer	(	PMC_Type *	base,
		const pmc_bandgap_buffer_config_t *	config
	)

This function configures the PMC bandgap, including the drive select and behavior in low-power mode.

Parameters

base	PMC peripheral base address.
config	Pointer to the configuration structure

static bool PMC_GetPeriphIOIsolationFlag ( PMC_Type * base )

inlinestatic

This function reads the Acknowledge Isolation setting that indicates whether certain peripherals and the I/O pads are in a latched state as a result of having been in the VLLS mode.

Parameters

base	PMC peripheral base address.
base	Base address for current PMC instance.

Returns: ACK isolation 0 - Peripherals and I/O pads are in a normal run state. 1 - Certain peripherals and I/O pads are in an isolated and latched state.

static void PMC_ClearPeriphIOIsolationFlag ( PMC_Type * base )

inlinestatic

This function clears the ACK Isolation flag. Writing one to this setting when it is set releases the I/O pads and certain peripherals to their normal run mode state.

Parameters

base	PMC peripheral base address.

static bool PMC_IsRegulatorInRunRegulation ( PMC_Type * base )

inlinestatic

This function returns the regulator to run a regulation status. It provides the current status of the internal voltage regulator.

Parameters

base	PMC peripheral base address.
base	Base address for current PMC instance.

Returns: Regulation status 0 - Regulator is in a stop regulation or in transition to/from the regulation. 1 - Regulator is in a run regulation.
