The serial communications interface (SCI) allows asynchronous serial
communications with peripheral devices and other microcontroller units
(MCU).
The MMC2114, MMC2113, and MMC2112 have two identical SCI
modules, each with its own control registers and input/output (I/O) pins.
In the text that follows, SCI register names are denoted generically.
Thus, SCIPORT refers interchangeably to SCI1PORT and SCI2PORT,
the port data registers for SCI1 and SCI2, respectively.
