6.4.2 Serial Communication Interface (SCI)
The
Serial
Communication
Interface
allows
asynchronous communication. It can communicate with a
UART = Universal Asynchronous Receiver Transmitter,
ACIA = Asynchronous Communication Interface Adapter
and all other chips that employ standard asynchronous serial
communication. The serial communication interface has
following characteristics:
Half duplex.
Standard NRZ format.
Start bit, 8 data bits and 1 stop bit.
Hardware programmable baudrate (4800, 9600,
19200 and 38400 baud).
05 V levels with open drain for TxD.
05 V levels for RxD and T_REQ.
