Am186™CC/CH/CU Microcontrollers User’s Manual
■
Chapter 7, “Interrupts,” describes the microcontrollers’ support for interrupts, both
maskable and nonmaskable. It discusses interrupt sequence and priority as well as how
to configure the maskable interrupt sources through the interrupt channels. It also
describes the nonmaskable interrupts.
■
Chapter 8, “DMA Controller,” describes how to use the DMA channels (general-purpose
and SmartDMA channels) to transfer data between memory and internal and external
peripherals.
■
Chapter 9, “Programmable I/O Signals,” discusses the user programmable input/output
signals (PIOs).
■
Chapter 10, “Programmable Timers,” tells how to use the programmable timers for the
following tasks: counting or timing external events, generating nonrepetitive or variable-
duty-cycle waveforms, generating interrupts, supporting real-time coding and time-delay
applications through polling, prescaling the other timer, requesting DMA, or measuring
pulse widths (as a PWD).
■
Chapter 11, “Watchdog Timer,” describes how to use the watchdog timer to generate
nonmaskable interrupts (NMIs), microcontroller resets, and system resets when the
programmable time-out value is reached.
■
Chapter 12, “Serial Communications Overview,” discusses the serial communications
features of the microcontrollers and their trade-offs, and provides a brief overview of
serial communications.
■
Chapter 13, “Asynchronous Serial Ports (UARTs),” describes how to use the UART and
High-Speed UART for asynchronous serial data transfer.
■
Chapter 14, “Synchronous Serial Port (SSI),” discusses how to use the SSI synchronous
serial port to provide half-duplex, bidirectional communications between the
microcontrollers and other system components
■
Chapter 15, “High-Level Data Link Control (HDLC),” provides a brief overview of HDLC
and describes how to configure the HDLC channels to support data movement in a
variety of applications.
■
Chapter 16, “HDLC External Serial Interface Configuration (TSAs),” describes how to
use the time-division multiplex features to configure the HDLC external serial interfaces.
Each Time-Slot Assigner (TSA) can be programmed to select between raw DCE and
dedicated PCM Highway external interfaces, as well as to multiplex GCI/PCM Highway
data.
■
Chapter 17, “General Circuit Interface (GCI),” discusses how to configure the GCI
controller for a GCI interface on HDLC Channel A, or multiplexed GCI/PCM Highway
interfaces to the other channels
■
Chapter 18, “Universal Serial Bus (USB),” covers the highly flexible integrated USB
peripheral controller and how to implement a variety of microcontroller-based USB
peripheral devices for telephony, audio, or other high-end applications.
■
Appendix A, “Register Summary,” provides a summary of all the microcontroller
peripheral control block (PCB) registers, listed in offset order.
■
The Glossary provides definitions of significant terms used in this manual.
■
The Index contains extensive references to make it easier to find specific information.
