PREFACE

Users:

This manual is aimed at engineers who need to be familiar with the capabilities of the

µPD78214 sub-series for

application program development purposes.

Purpose:

The purpose of this manual is to help users understand the hardware capabilities of the

µPD78214 sub-series.

Organization:

Two manuals are available for the

µPD78214 sub-series: The hardware manual (this manual) and instruction

manual (common to all 78K/II series products). The contents of the manuals are:

Hardware

Instruction

Pin functions

CPU functions

Internal block functions

Addressing

Interrupt functions

Instruction set

Other built-in functions

Important information related to using the products described in this manual is provided in the form of
“Caution” notes, appearing in appropriate places in each chapter. Each “Caution” is repeated at the end
of the chapter. Be careful to observe these notes when using the products.

Guidance:

Readers of this manual are assumed to have a general knowledge of electronics, logical circuits, and microcom-
puters.

When using this manual with the

µPD78212, µPD78213, µPD78P214, µPD78212(A), µPD78213(A), µPD78214(A), or

µPD78P214(A):
This manual describes the functions of the

µPD78212, µPD78213, µPD78214, µPD78P214, µPD78212(A), µPD78213(A),

µPD78214(A), and µPD78P214(A). The relationships between these products are shown in the figure on the next
page. Where there is no functional difference between the products, only the

µPD78214 is described, that

description also being applicable to the

µPD78212, µPD78213, µPD78P214, µPD78212(A), µPD78213(A), µPD78214(A),

and

µPD78P214(A).

The examples given in this manual are prepared for “Standard” quality products for general electronics
devices. If customers intend to use the examples in this manual in fields where the “Special” quality is
required, note the quality grade of the parts and circuits actually used.
