Intel 8XC196MH, 8XC196MD, 8XC196MC manual Special Operating Modes

8XC196MC, MD, MH USER’S MANUAL

Chapter 9 — Waveform Generator — describes the waveform generator and explains how to configure it. For additional information and application examples, consult AP-483, Application Examples Using the 8XC196MC/MD Microcontroller (order number 272282).

Chapter 10 — Pulse-width Modulator — provides a functional overview of the pulse width modulator (PWM) modules, describes how to program them, and provides sample circuitry for converting the PWM outputs to analog signals.

Chapter 11 — Event Processor Array (EPA) — describes the event processor array, a tim- er/counter-based, high-speed input/output unit. It describes the timer/counters and explains how to program the EPA and how to use the EPA to produce pulse-width modulated (PWM) outputs.

Chapter 12 — Analog-to-digital (A/D) Converter — provides an overview of the analog-to- digital (A/D) converter and describes how to program the converter, read the conversion results, and interface with external circuitry.

Chapter 13 — Minimum Hardware Considerations — describes options for providing the ba-

sic requirements for device operation within a system, discusses other hardware considerations, and describes device reset options.

Chapter 14 — Special Operating Modes —	provides an overview of the idle, powerdown,
and on-circuit emulation (ONCE) modes and describes how to enter and exit each mode.
Chapter 15 — Interfacing with External Memory —		lists the external memory signals and de-

scribes the registers that control the external memory interface. It discusses the bus width and memory configurations, the bus-hold protocol, write-control modes, and internal wait states and ready control. Finally, it provides timing information for the system bus.

Chapter 16 — Programming the Nonvolatile Memory — provides recommended circuits, the corresponding memory maps, and flow diagrams. It also provides procedures for auto program- ming.

Appendix A — Instruction Set Reference — provides reference information for the instruction set. It describes each instruction; defines the processor status word (PSW) flags; shows the rela- tionships between instructions and PSW flags; and lists hexadecimal opcodes, instruction lengths, and execution times. (For additional information about the instruction set, see Chapter 3, “Programming Considerations.”)

Appendix B — Signal Descriptions — provides reference information for the device pins, in- cluding descriptions of the pin functions, reset status of the I/O and control pins, and package pin assignments.
