the MPC561/MPC563 to an external device; and shorts internal signals to increase access to
multiple functions multiplexed on the same external signal.
•
Chapter 19, “Time Processor Unit 3
,” describes an enhanced version of the original TPU, an
intelligent, semi-autonomous microcontroller designed for timing control.
•
Chapter 20, “Dual-Port TPU3 RAM (DPTRAM)
.” The dual-port RAM (DPTRAM) module
consists of a control register block and an 8-Kbyte array of static RAM that can be used either as
microcode storage for the TPU3 or as general-purpose memory. The MPC561/MPC563 has one
DPTRAM module that serves two TPU3 modules.
•
Chapter 21, “CDR3 Flash (UC3F) EEPROM
.” The MPC563 U-bus CDR3 (UC3F) EEPROM
module is designed for use in embedded microcontroller applications targeted for high-speed read
performance and high-density byte count requirements.
•
.” This module provides the MPC561/MPC563 with a general
purpose memory that may be read from or written to as either bytes, half-words, or words. In
addition to this, a portion of the CALRAM, called the overlay region, can be used for calibration
(i.e., overlaying portions of the U-bus Flash with a portion of the CALRAM array).
•
Chapter 23, “Development Support
,” covers program flow tracking support,
breakpoint/watchpoint support, development system interface support (debug mode) and software
monitor debugger support. These features allow efficiency in debugging systems based on the
MPC561/MPC563.
•
.” The READI module provides development support capabilities for
MCUs in single chip mode, without requiring address and data signals for internal visibility.
•
Chapter 25, “IEEE 1149.1-Compliant Interface (JTAG)
,” describes MPC561/MPC563
compatibility with the IEEE 1149.1 Standard Test Access Port and Boundary Scan Architecture as
well as any potential incompatibility issues.
•
Appendix A, “MPC562/MPC564 Compression Features
,” includes information about code
compression features of the MPC562/MPC564.
•
Appendix B, “Internal Memory Map
,” provides memory maps for the MPC561/MPC563 modules.
•
Appendix C, “Clock and Board Guidelines
.” The MPC561/MPC563 built-in PLL, oscillator, and
other analog and sensitive circuits require that the board design follow special layout guidelines to
ensure proper operation of the chip clocks. This appendix describes how the clock supplies and
external components should be connected in a system.
•
Appendix D, “TPU3 ROM Functions
,” provides a brief description of the pre-programmed
functions in the TPU3.
•
Appendix E, “Memory Access Timing
,” lists memory access timings for internal and external
memory combinations.
•
Appendix F, “Electrical Characteristics
,” contains detailed information on power considerations,
DC/AC electrical characteristics, and AC timing characteristics of the MPC561/MPC563 at the
default 40 MHz and optional 56 MHz operating frequencies.
•
Appendix G, “66-MHz Electrical Characteristics
,” contains detailed information on power
considerations, DC/AC electrical characteristics, and AC timing characteristics of the
MPC561/MPC563 at the optional operating frequency of 66 MHz.
This document also includes a register index and comprehensive index.
