PREFACE
INTRODUCTION
COMM86 FAMILY
The Am186™CC communications controller, Am186CH HDLC microcontroller, and
Am186CU USB microcontroller, the first members of the AMD Comm86™ family, are cost-
effective, high-performance embedded microcontroller solutions for communications
applications. These highly integrated microcontrollers enable customers to save system
costs and increase performance over 8-bit microcontrollers and other 16-bit
microcontrollers.
All of these microcontrollers offer the advantages of the x86 development environment’s
widely available native development tools, applications, and system software. Additionally,
the microcontrollers use the industry-standard 186 instruction set that is part of the AMD
E86™ family, which continually offers instruction-set-compatible upgrades. Built into each
of the microcontrollers is a wide range of communications features required in many
communications applications.
PURPOSE OF THIS MANUAL
This manual describes the technical features and programming interface of the Am186CC,
Am186CH, and Am186CU microcontrollers.
Intended Audience
The
Am186CC/CH/CU Microcontrollers User’s Manual, order #21914, is intended for
computer software and hardware engineers and system architects who are designing or
are considering designing systems based on one of these controllers.
Overview of this Manual
This manual is organized into the following chapters:
■
Chapter 1, “Architectural Overview,” provides an overview of the features of the
microcontrollers, including a block diagram and sample application diagrams.
■
Chapter 2, “Configuration Basics,” provides basic information about configuring the
microcontrollers, including discussions of the registers, memory organization, address
generation, I/O space, peripheral control block, instruction set, segments, data types,
and addressing modes.
■
Chapter 3, “System Overview,” contains descriptions of the microcontrollers’ system
configuration registers, initialization and processor reset, signals, bus interface, and
clock control.
■
Chapter 4, “Emulator Support,” describes the various features available in the
microcontrollers to facilitate the design and operation of In-Circuit Emulators, and
discusses common concerns shared among emulator developers.
■
Chapter 5, “Chip Selects,” describes the six chip selects provided for use with memory
devices and the eight provided for use with peripherals in either memory or I/O space.
■
Chapter 6, “DRAM Controller,” discusses the fully integrated DRAM controller that
provides a glueless interface to 40-, 50-, 60-, and 70-ns Extended Data Out (EDO)
DRAM.
