Detailed Description

STOP Mode functions.

 ===============================================================================
                        ##### STOP Mode functions #####
 ===============================================================================
    [..] This subsection provides a set of functions allowing to manage 
         WakeUp from STOP mode.

    [..] The USART is able to WakeUp from Stop Mode if USART clock is set to HSI
         or LSI.
         
    [..] The WakeUp source is configured by calling USART_StopModeWakeUpSourceConfig()
         function.
         
    [..] After configuring the source of WakeUp and before entering in Stop Mode 
         USART_STOPModeCmd() function should be called to allow USART WakeUp.

Function Documentation

void USART_STOPModeCmd	(	USART_TypeDef *	USARTx,
		FunctionalState	NewState
	)

Enables or disables the specified USART peripheral in STOP Mode.

Parameters

USARTx,:	where x can be 1 to select the USART peripheral.
NewState,:	new state of the USARTx peripheral state in stop mode. This parameter can be: ENABLE or DISABLE.

Note

This function has to be called when USART clock is set to HSI or LSE.

Return values

None

void USART_StopModeWakeUpSourceConfig	(	USART_TypeDef *	USARTx,
		uint32_t	USART_WakeUpSource
	)

Selects the USART WakeUp method form stop mode.

Parameters

USARTx,:	where x can be 1 to select the USART peripheral.
USART_WakeUp,:	specifies the selected USART wakeup method. This parameter can be one of the following values: USART_WakeUpSource_AddressMatch: WUF active on address match. USART_WakeUpSource_StartBit: WUF active on Start bit detection. USART_WakeUpSource_RXNE: WUF active on RXNE.

Note

This function has to be called before calling USART_Cmd() function.

Return values

None
