The serial communications interface (SCI) is a universal asynchronous
receiver transmitter (UART), one of two independent serial input/output
(I/O) subsystems in the M68HC11 E series of microcontrollers. It has a
standard non-return-to-zero (NRZ) format (one start bit , eight or nine
data bits, and one stop bit). Several baud rates are available. The SCI
