这是一个老外在编写Uart收发器时阐述的:
When both transmit and receive operations are scheduled for the same timer
interrupt, priority is given to the transmitter routine. The reason for this
is that a great deal of jitter can be tolerated in the timing of the received
bit sampling, but the transmitted data must "look" good to the outside world.
