DESCRIPTION
The Philips Semiconductors SC26C562 Dual Universal Serial
Communications Controller (CDUSCC) is a single-chip CMOS-LSI
communications device that provides two independent,
multi-protocol, full-duplex receiver/transmitter channels in a single
package. It supports bit-oriented and character-oriented (byte count
and byte control) synchronous data link controls as well as
asynchronous protocols. The SC26C562 interfaces to synchronous
bus MPUs and is capable of program-polled, interrupt driven,
block-move or DMA data transfers.
The SC26C562 (CDUSCC) is (PIN) hardware and (REGISTER)
software compatible with the existing SCN26562 (DUSCC).
CDUSCC will automatically configure to the NMOS DUSCC register
map (default mode) on power up.
The operating mode and data format of each channel can be
programmed independently. Each channel consists of a receiver, a
transmitter, a 16-bit multifunction counter/timer, a digital
phase-locked loop (DPLL), a parity/CRC generator and checker, and
associated control circuits. The two channels share a common bit
rate generator (BRG), operating directly from a crystal or an external
clock, which provides sixteen common bit rates simultaneously. The
operating rate for the receiver and transmitter of each channel can
be independently selected from the BRG, the DPLL, the
counter/timer, or from an external 1X or 16X clock, making the
CDUSCC well-suited for dual-speed channel applications. Data
rates up to 10Mbits per second are supported.
The transmitter and receiver each contain a sixteen-deep FIFO with
appended transmitter command and receiver status bits and a shift
register. This permits reading and writing of up to sixteen characters
at a time, minimizing the potential of receiver overrun or transmitter
underrun, and reducing interrupt or DMA overhead. In addition, a
flow control capability is provided to disable a remote transmitter
when the FIFO of the local receiving device is full.
Two modem control inputs (DCD and CTS) and three modem
control outputs (RTS and two general purpose) are provided.
Because the modem control inputs and outputs are general purpose
in nature, they can be optionally programmed for other functions.
The SC26C562 CDUSCC is optimized to interface with processors
using a synchronous bus interface, such as the 8086, and iAPX86
family. For systems using an asynchronous bus, such as the 68000
and 68010, refer to the SC68C562 documentation.
Refer to the CMOS Dual Universal Serial Communication Controller
(CDUSCC) User’s Manual for a complete operational description.
