The MC1323x has one serial communications interface module — sometimes called a universal
asynchronous receiver/transmitter (UART). Typically, this port is used to connect to the RS232 serial
input/output (I/O) port of a personal computer or workstation, and it can also be used to communicate with
other embedded controllers.
The SCI module has a single, flexible frac-N (13-bit modulo counter, 5-bit fractional counter) baud rate
generator used both for transmit and receive. With a maximum 16 MHz peripheral clock, baud rates as
high as 1 Mbps can be supported (standard is 921,600 baud).
This SCI system offers many advanced features not commonly found on other asynchronous serial I/O
peripherals on other embedded controllers. The receiver employs an advanced data sampling technique
that ensures reliable communication and noise detection. Hardware parity, receiver wake-up, and double
buffering on transmit and receive are also included.

KBI1 has eight keyboard interrupt pins with individual pin enable bits.
KBI2 has four keyboard interrupt pins with individual pin enable bits.
Supports up to a 12x12 keyboard matrix. A 6x6 matrix can be supported without impacting other
I/O functions.
Each keyboard interrupt pin is programmable as falling edge (or rising edge) only, or both falling
edge and low level (or both rising edge and high level) interrupt sensitivity. Pull-ups and
pull-downs enabled by selected mode.
Individual signal software enabled interrupts for both KBI1 and KBI2.
Can be used for device wake-up
Full-duplex, standard non-return-to-zero (NRZ) format
Double-buffered transmitter and receiver with separate enables
Programmable high accuracy baud rates (frac-N generator)
Interrupt-driven or polled operation:
— Transmit data register empty and transmission complete
