PREFACE
■Objectives and Intended Reader
The MB89950/950A series has been developed as a general-purpose version of the F2MC-8L family
consisting of proprietary 8-bit, single-chip microcontrollers. The MB89950/950A series is applicable to a
wide range of applications from consumer products to industrial equipment, including portable devices.
This manual describes the functions and operation of the MB89950/950A series and is aimed at engineers
using the MB89950/950A series of microcontrollers to develop actual products. See the F2MC-8L MB89600
Series Programming Manual for details on the MB89950/950A instruction set.
■Trademarks
F2MC is the abbreviation of FUJITSU Flexible Microcontroller.
Other system and product names in this manual are trademarks of respective companies or organizations.
The symbols TM and ® are sometimes omitted in this manual.

READING THIS MANUAL
■Notations of the Register Name and Pin Name
●Example for description of register name and bit name
●Notations of a double-purpose pin
P22/SCK pin
Some pins can be used by switching their functions using, for example, settings by a program. Each
double-purpose pin is represented by separating the name of each function using "/".
