INTRODUCTION
Readers
This manual is intended for user engineers who understand the functions of the
μ
PD789217Y Subseries to design and develop its application systems and
programs.
Target products:
μ
PD789197Y Subseries:
μ
PD789196Y,
μ
PD789197Y, and
μ
PD78F9197Y
μ
PD789217Y Subseries:
μ
PD789216Y,
μ
PD789217Y, and
μ
PD78F9217Y
Unless otherwise specified, the
μ
PD789217Y Subseries
is treated as the
representative product in this manual.
The oscillation frequency of the main system clock is regarded as f
X
for
ceramic/crystal oscillation (
μ
PD789197Y Subseries), and regarded as f
CC
for an RC
oscillation (
μ
PD789217Y Subseries).
Purpose
This manual is intended for users to understand the functions described in the
Organization below.
