Structure of the
diagram
In the diagram, the building blocks are grouped according to their function.
At the top of the diagram, you find the functions for controlling power supply
and reset.
The upper right-hand section shows the building blocks of the CPU system and
the memory interface components. The I/O ports are summarized below that
section.
The left-hand section of the block diagram identifies the interfaces to
peripherals and also the built-in timers. All these components are connected to
and can be controlled via the internal bus.
The Clock Generator, depicted in the lower right-hand section, plays a central
role. It generates and monitors not only the clocks for the CPU and the
peripheral interfaces, but also governs the power save modes that can be
entered when the device is not in use.
Structure of the
manual
This manual explains how to use the V850E/Dx3 microcontroller devices. It
provides comprehensive information about the building blocks, their features,
and how to set registers in order to enable or disable specific functions.
The manual provides individual chapters for the building blocks. These
chapters are organized according to the grouping in the diagram.
