xxviii MC68VZ328 User’s Manual
Chapter 9 Interrupt Controller: This chapter provides a description and operational
considerations for interrupt controller operation. It includes a description of the
vector generator and pen and keyboard interrupts.
Chapter 10 I/O Ports: This chapter covers all 76 GPIO lines found in the MC68VZ328.
Because each pin is individually configurable, a detailed description of the
operation of and programming information for each pin is provided.
Chapter 11 Real-Time Clock: This chapter describes the ope ration of the real-time clock
(RTC) module, which is composed of a prescaler , time-of-day (T OD) clock, T OD
alarm, programmable real-time interrupt, watchdog timer, and minute stopw atch
as well as control registers and bus interface hard ware.
Chapter 12 General-Purpose Timers: This chapter describes the two 16-bit timers that can
be used as both watchdogs and alarms. It also describes how the timers can be
combined into a single 32-bit timer.
Chapter 13 Serial Peripheral Interface 1 and 2: This chapter describes the features of the
DragonBall VZ’s two serial peripheral interfaces and how they are used to
communicate with external devices.
Chapter 14 Universal Asynchronous Receiver/Transmitter 1 and 2: The two universal
asynchronous receiver/transmitter (UAR T) ports allo w the incorpor ation of seri al
communication in existing and new designs. This section describes how data is
transported in character blocks using the standard “start-stop” format. It also
discusses how to configure and program the UART modules.
Chapter 15 Pulse-Width Modulator 1 and 2: This chapter describes both pulse-width
modulators. Programming information is also provided.
Chapter 16 In-Circuit Emulation: This chapter describes the in -circuit emulation (ICE)
module and how it is used to support low-cost emulator designs for the
MC68VZ328 microprocessor.
Chapter 17 Bootstrap Mode: The operation of bootstrap models is described in detai l in this
chapter. This chapter describes programming information necessary to allow a
system to initialize a target system and downlo ad a program or data to the target
system’s RAM using the UART1 or UART2 controller.
Chapter 18 Application Guide: This chapter contains information that will assist during the
integration of the MC68VZ328 into an existing or a new design. It includes a
design checklist and instructions for using the MC68VZ328 Application
Development System (ADS) board to get started with the design process.
Chapter 19 Electrical Characteristics: This chapter describes the electrical characteristics
of the MC68VZ328 integrated processor.
Chapter 20 Mechanical Data and Ordering Information: This chapter provides
mechanical data, including illustrations, and ordering information.
