Description

Inter-integrated Circuit (I2C) Peripheral API.

This module contains functions to control the I2C peripheral of Silicon Labs 32-bit MCUs and SoCs. The I2C interface allows communication on I2C buses with the lowest energy consumption possible.

Data Structures
struct	I2C_Init_TypeDef
	I2C initialization structure.

struct	I2C_TransferSeq_TypeDef
	Master mode transfer message structure used to define a complete I2C transfer sequence (from start to stop).

Functions
uint32_t	I2C_BusFreqGet (I2C_TypeDef *i2c)
	Get the current configured I2C bus frequency.

void	I2C_BusFreqSet (I2C_TypeDef *i2c, uint32_t freqRef, uint32_t freqScl, I2C_ClockHLR_TypeDef i2cMode)
	Set the I2C bus frequency.

void	I2C_Enable (I2C_TypeDef *i2c, bool enable)
	Enable/disable I2C.

void	I2C_Init (I2C_TypeDef i2c, const I2C_Init_TypeDef init)
	Initialize I2C.

void	I2C_IntClear (I2C_TypeDef *i2c, uint32_t flags)
	Clear one or more pending I2C interrupts.

void	I2C_IntDisable (I2C_TypeDef *i2c, uint32_t flags)
	Disable one or more I2C interrupts.

void	I2C_IntEnable (I2C_TypeDef *i2c, uint32_t flags)
	Enable one or more I2C interrupts.

uint32_t	I2C_IntGet (I2C_TypeDef *i2c)
	Get pending I2C interrupt flags.
