VCMP - Voltage Comparator

Description

Supply Voltage Comparator (VCMP) Peripheral API.

This module contains functions to control the VCMP peripheral of Silicon Labs 32-bit MCUs and SoCs. The VCMP monitors the input voltage supply and generates interrupts on events using as little as 100 nA.

Data Structures
struct	VCMP_Init_TypeDef
	VCMP Initialization structure.

Functions
void	VCMP_Init (const VCMP_Init_TypeDef *vcmpInit)
	Configure and enable Voltage Comparator.
void	VCMP_LowPowerRefSet (bool enable)
	Enable or disable Low Power Reference setting.
void	VCMP_TriggerSet (int level)
	Configure the trigger level of the voltage comparator.
void	VCMP_Enable (void)
	Enable Voltage Comparator.
void	VCMP_Disable (void)
	Disable Voltage Comparator.
uint32_t	VCMP_VoltageToLevel (float v)
	Calculate voltage to trigger level.
bool	VCMP_VDDLower (void)
	Check if VDD is lower than trigger level.
bool	VCMP_VDDHigher (void)
	Check if VDD is higher than trigger level.
bool	VCMP_Ready (void)
	Check if VCMP output is ready.
void	VCMP_IntClear (uint32_t flags)
	Clear one or more pending VCMP interrupts.
void	VCMP_IntSet (uint32_t flags)
	Set one or more pending VCMP interrupts from SW.
void	VCMP_IntDisable (uint32_t flags)
	Disable one or more VCMP interrupts.
void	VCMP_IntEnable (uint32_t flags)
	Enable one or more VCMP interrupts.
uint32_t	VCMP_IntGet (void)
	Get pending VCMP interrupt flags.
uint32_t	VCMP_IntGetEnabled (void)
	Get enabled and pending VCMP interrupt flags.

Macros
#define	VCMP_INIT_DEFAULT
	Default VCMP initialization structure.
