+* Notes:
+* - PE (Parity error), FE (Framing error), NE (Noise error),
+* ORE (OverRun error) and IDLE (Idle line detected)
+* pending bits are cleared by software sequence: a read

+* (USART_ReceiveData()).
+* - RXNE pending bit can be also cleared by a read to the

+* - TC pending bit can be also cleared by software
+* sequence: a read operation to USART_SR register
