SCC68692
Dual asynchronous receiver/transmitter (DUART)

DESCRIPTION
The Philips Semiconductors SCC68692 Dual Universal
Asynchronous Receiver/Transmitter (DUART) is compatible with
SCN68681. It is a single-chip CMOS-LSI communications device
that provides two full-duplex asynchronous receiver/transmitter
channels in a single package. It is compatible with other S68000
family devices and can also interface easily with other
microprocessors. The DUART can be used in a polled or interrupt
driven systems.
The operating mode and data format of each channel can be
programmed independently. Additionally, each receiver and
transmitter can select its operating speed as one of eighteen fixed
baud rates, a 16X clock derived from a programmable counter/timer,
or an external 1X or 16X clock. The baud rate generator and
counter/timer can operate directly from a crystal or from external
clock inputs. The ability to independently program the operating
speed of the receiver and transmitter make the DUART particularly
attractive for dual-speed channel applications such as clustered
terminal systems.
Each receiver is quadruple buffered to minimize the potential of
receiver over-run or to reduce interrupt overhead in interrupt driven
systems. In addition, a flow control capability is provided to disable a
remote DUART transmitter when the receiver buffer is full.
Also provided on the SCC68692 are a multipurpose 6-bit input port
and a multipurpose 8-bit output port. These can be used as general
purpose I/O ports or can be assigned specific functions (such as
clock inputs or status/interrupt outputs) under program control.
