Serial Communications Interface Modules (SCI1 and SCI2)
The receiver can handle either 8-bit or 9-bit data. The state of the M bit
in SCICR1 selects frame length. When receiving 9-bit data, bit R8 in
SCIDRH is the ninth bit (bit 8).
When the SCI receives a frame, the receive shift register shifts the frame
in from the RXD pin.
