DESCRIPTION
The Philips Semiconductors SCN2661 EPCI is a universal
synchronous/asynchronous data communications controller chip
that is an enhanced version of the SCN2651. It interfaces easily to
all 8-bit and 16-bit microprocessors and may be used in a polled or
interrupt driven system environment. The SCN2661 accepts
programmed instructions from the microprocessor while supporting
many serial data communications disciplines —synchronous and
asynchronous — in the full- or half-duplex mode. Special support
for BISYNC is provided.
The EPCI serializes parallel data characters received from the
microprocessor for transmission. Simultaneously, it can receive
serial data and convert it into parallel data characters for input to the
microcomputer.
The SCN2661 contains a baud rate generator which can be
programmed to either accept an external clock or to generate
internal transmit or receive clocks. Sixteen different baud rates can
be selected under program control when operating in the internal
clock mode. Each version of the EPCI (A, B, C) has a different set
of baud rates.
