Serial Communications Interface Modules (SCI1 and SCI2)
After an entire frame shifts into the receive shift register, the data portion
of the frame transfers to SCIDRH and SCIDRL. The RDRF flag is set,
indicating that the received data can be read. If the RIE bit is also set,
RDRF generates an interrupt request.
The receiver samples the RXD pin at the RT clock rate. The RT clock is
an internal signal with a frequency 16 times the baud rate. To adjust for
baud rate mismatch, the RT clock resynchronizes:
To locate the start bit, data recovery logic does an asynchronous search
for a 0 preceded by three 1s. When the falling edge of a possible start bit
occurs, the RT clock begins to count to 16.

After every start bit
After the receiver detects a data bit change from logic 1 to logic 0
(after the majority of data bit samples at RT8, RT9, and RT10
returns a valid logic 1 and the majority of the next RT8, RT9, and
RT10 samples returns a valid logic 0)
