7.3.5 Receive operation
When the receive conditions listed on page 7-25 are satisfied, the UARTi enters the receive enable state.
The receive operations are described below.
The receive complete flag is cleared to “0” when the low-order byte of the UARTi receive buffer register
is read out. Figure 7.3.10 shows the receive operation, and Figure 7.3.11 shows an example of receive
timing (when selecting an external clock).
The contents of the UARTi receive register are shifted by 1 bit to the right.
