GENERAL DESCRIPTION

The Zilog Enhanced Mono Serial Communication-

Controller, Z85233 EMSCC, is a software compat-

ible CMOS member of the SCC family introduced

by Zilog in 1981. The EMSCC is a full-duplex data

communications controller capable of supporting a

wide range of popular protocols. The Z85233

EMSCC is a single channel version (Channel A) of

Zilog's Z85230 ESCC. Based on Zilog's unique

Superintegration™ Technology, the EMSCC is

compatible with designs using Zilog's SCC and

ESCC to receive and transmit data. It has many

improvements that significantly reduce CPU over-

head. The addition of a 4-byte transmit FIFO and

an 8-byte receive FIFO significantly reduces the

overhead required to provide data to, and get data-

from, the transmitter and receiver.

The EMSCC also has many features that improve

packet handling in SDLC mode. The EMSCC will

New Programmable Features Added with

Write Register 7'

Write registers: WR3, WR4, WR5, and WR10

A Full-Duplex Channel with a Crystal Oscilla-

tor, Baud Rate Generator, and Digital Phase-

Locked Loop.
