5 SERIAL COMMUNICATIONS INTERFACE
This section contains a description of the serial communication interface (SCI).
5.1 Overview and Features
A full-duplex asynchronous Serial Communications Interface (SCI) is provided with a
standard NRZ format (one start bit, eight or nine data bits, and one stop bit) and a va-
riety of baud rates. The SCI transmitter and receiver are functionally independent, but
use the same data format and bit rate. “Baud” and “bit rate” are used synonymously in
the following description.
5.1.1 SCI Two-Wire System Features
Standard NRZ (mark/space) format.
Advanced error detection method includes noise detection for noise duration of
up to 1/16 bit time.
Full-duplex operation.
Software programmable for one of 32 different baud rates.
Software selectable word length (eight or nine bit words).
Separate transmitter and receiver enable bits.
Capable of being interrupt driven.
Four separate enable bits available for interrupt control.
5.1.2 SCI Receiver Features
Receiver wake-up function (idle or address bit).
Idle line detect.
Framing error detect.
Noise detect.
Overrun detect.
Receiver data register full flag.
5.1.3 SCI Transmitter Features
Transmit data register empty flag.
Transmit complete flag.
Send break.
5.2 Data Format
Receive data or transmit data is the serial data which is transferred to the internal data
bus from the receive data input pin (RxD), or from the internal bus to the transmit data
output pin (TxD).
The non-return-to-zero (NRZ) data format shown in
Figure 5-1
is used and must meet
the following criteria:
