PREFACE
I Objectives and Intended Reader
The MB89950/950A series has been developed as a general-purpose version of the F
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 F
Series Programming Manual for details on the MB89950/950A instruction set.
