USART driver

The STM32F3xx USART includes enhancements in comparison with STM32F10x USART.

Table9. presents the USART driver API correspondence between STM32F10x and

STM32F3xx Libraries.

It is applicable only for STM32F30xx devices.

One more flag in STM32F3xx (TI frame format error) can generate an event in comparison with STM32F10x driver API.
