Serial Communications Interface (S08SCIV4)
14.1
The MC9S08JM16 series include two independent serial communications interface (SCI) modules, which
are sometimes called universal asynchronous receiver/transmitters (UARTs). Typically, these systems are
used to connect to the RS232 serial input/output (I/O) port of a personal computer or workstation, but they
can also be used to communicate with other embedded controllers.
A flexible, 13-bit, modulo-based baud rate generator supports a broad range of standard baud rates beyond
115.2 kbaud. Transmit and receive within the same SCI use a common baud rate, and each SCI module
has a separate baud rate generator.
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 wakeup, and double
buffering on transmit and receive are also included.

Introduction
MC9S08JM16 series devices operate at a higher voltage range (2.7 V to
5.5 V) and do not include stop1 mode. Therefore, please disregard
references to stop1.
