Function Name
void USART_StopModeWakeUpSourceConfig (
USART_TypeDef * USARTx, uint32_t USART_WakeUpSource)
Function Description
Selects the USART WakeUp method form stop mode.
Parameters
 USARTx : Select the USART peripheral. This parameter can
be one of the following values: USART1 or USART2 or
USART3 or UART4 or UART5.
 USART_WakeUp : specifies the selected USART wakeup
method. This parameter can be one of the following values:
