5.5 SERIAL COMMUNICATIONS INTERFACE (SCI)
5.5.1 Introduction
The Serial Communications Interface (SCI) offers
a flexible means of full-duplex data exchange with
external equipment requiring an industry standard
NRZ asynchronous serial data format.
5.5.2 Main Features
I
Full duplex, asynchronous communications
I
NRZ standard format (Mark/Space)
I
Independently programmable transmit and
receive baud rates up to 250K baud.
I
Programmable data word length (8 or 9 bits)
I
Receive buffer full, Transmit buffer empty and
End of Transmission flags
I
Two receiver wake-up modes:
– Address bit (MSB)
– Idle line
I
Muting function for multiprocessor configurations
I
Separate enable bits for Transmitter and
Receiver
I
Three error detection flags:
– Overrun error
– Noise error
– Frame error
I
Five interrupt sources with flags:
– Transmit data register empty
– Transmission complete
– Receive data register full
– Idle line received
– Overrun error detected
5.5.3 General Description
The interface is externally connected to another
device by two pins (see Figure 1):
– TDO: Transmit Data Output. When the transmit-
ter is disabled, the output pin returns to its I/O
port configuration. When the transmitter is ena-
bled and nothing is to be transmitted, the TDO
pin is at high level.
– RDI: Receive Data Input is the serial data input.
Oversampling techniques are used for data re-
covery by discriminating between valid incoming
data and noise.
Through this pins, serial data is transmitted and re-
ceived as frames comprising:
– An Idle Line prior to transmission or reception
– A start bit
– A data word (8 or 9 bits) least significant bit first
– A Stop bit indicating that the frame is complete.
