The multiple serial interface (MSI) module consists of three independent
serial I/O sub-systems: two serial communication interfaces (SCI0 and
SCI1) and the serial peripheral interface (SPI). Each serial pin shares
function with the general-purpose port pins of port S. The SCI
subsystems are NRZ type systems that are compatible with standard
RS-232 systems. These SCI systems have a new 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.
