Serial Interface
14.1 Introduction
Each serial pin shares function with the general-purpose port pins of port S. The SCI is an NRZ
(non-return to zero) type system that is compatible with standard RS-232 systems. The SCI system has
a single-wire operation mode which allows the unused pin to be available as general-purpose I/O. The
SPI subsystem, which is compatible with the M68HC11 SPI, includes new features such as SS output
and bidirectional mode.
