PMC: Power Management Controller

Overview

The KSDK provides a Peripheral driver for the Power Management Controller (PMC) module of Kinetis devices. The PMC module contains internal voltage regulator, power on reset, low voltage detect system, and high voltage detect system.

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, enable interrupt or not, enable system reset or not.

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 enable interrupt or not.

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.
