I need some details about UART operation and timing, which are not clearly described in UM10601.  
What I think intuitively:
1. RXIDLE and RxRDY rising immediately after last sampling point of stop bit (9/16 of one bit interval after beginning of stop-bit interval).
2. RxIDLE falling and START rising at beginning of start-bit interval.
Am I right?
