Chapter 2 OVERVIEW
This Chapter provides an overview of the Oki
ML671000 CPU Board, its components, and its
functions.

Chapter 2 OVERVIEW
Page2-2
2.1 What is it?
The Oki ML671000 CPU Board is part of an emulation kit for developers debugging and
evaluating embedded user application systems to run on the ML671000, Oki Electric's high-
performance 32-bit single-chip microcontroller.
This document distinguishes two setups for debugging user application programs.
Angel mode (Note 1): Debugging with a direct link to the ARM Software Development Toolkit
(SDT) from Advanced RISC Machines Limited (ARM)
Normal embedded mode: Debugging with a link to the SDT through a JTAG communications
interface unit (Oki Electric ADI Board or ARM Multi-ICETM)
The Oki ML671000 CPU Board contains an ML671000 emulating the target device. It
replaces, however, the internal program ROM with rewritable emulation memory (SRAM).
Figure 2.1 shows the general Board layout.

As Figure 2.1 indicates, the user interface connectors provide access to most (See Note 1) of
the evaluation chip's I/O pins (Note 2). Connecting them to the user application program with
the optional user connector Board (USRCN) and user cable permits in-place debugging.

!
The Oki ML671000 CPU Board's Flash memory contains the Angel debugging monitor, for
use in developing applications based on the ARM CPU. For further details on this
program, refer to the ARM Software Development Toolkit User Guide and ARM Software
Development Toolkit Reference Guide.

!
The Oki ML671000 CPU Board sometimes handles the following ML671000 built-in
peripheral ports and pins differently: P0, P1.5, P1.6, P4.4, P4.5, P4.6, P4.7, P5.2, P5.3, P5.4,
P5.6, and P5.7. For further details, see Chapter 5 "Notes on Debugging."
