Description

Low Energy Universal Asynchronous Receiver/Transmitter (LEUART) Peripheral API.

This module contains functions to control the LEUART peripheral of Silicon Labs 32-bit MCUs and SoCs. The LEUART module provides the full UART communication using a low frequency 32.768 kHz clock and has special features for communication without the CPU intervention.

Data Structures
struct	LEUART_Init_TypeDef
	Initialization structure.

Functions
uint32_t	LEUART_BaudrateCalc (uint32_t refFreq, uint32_t clkdiv)
	Calculate the baudrate for the LEUART given reference frequency and clock division.

uint32_t	LEUART_BaudrateGet (LEUART_TypeDef *leuart)
	Get the current baudrate for LEUART.

void	LEUART_BaudrateSet (LEUART_TypeDef *leuart, uint32_t refFreq, uint32_t baudrate)
	Configure the baudrate (or as close as possible to a specified baudrate).

void	LEUART_Enable (LEUART_TypeDef *leuart, LEUART_Enable_TypeDef enable)
	Enable/disable the LEUART receiver and/or transmitter.

void	LEUART_FreezeEnable (LEUART_TypeDef *leuart, bool enable)
	LEUART register synchronization freeze control.

void	LEUART_Init (LEUART_TypeDef leuart, LEUART_Init_TypeDef const init)
