PREFACE
■The Purpose and Intended Readership of This Manual
Thank you very much for your continued special support for Fujitsu Semiconductor products.
The MB95630H Series is a line of products developed as general-purpose products in the New
8FX family of proprietary 8-bit single-chip microcontrollers applicable as application-specific
integrated circuits (ASICs). The MB95630H Series can be used for a wide range of
applications from consumer products including portable devices to industrial equipment.
Intended for engineers who actually develop products using the MB95630H Series of
microcontrollers, this manual describes its functions, features, and operations. You should read
through the manual.
This manual is written to explain the respective configurations and operations of peripheral
functions, but not to provide specifications of a device.
For detailed specifications of a device, refer to its data sheet.
For details on individual instructions, refer to "F2MC-8FX Programming Manual".
Note: F2MC is the abbreviation of FUJITSU Flexible Microcontroller.
■Trademark
The company names and brand names in this document are the trademarks or registered
trademarks of their respective owners.
■Sample Programs
Fujitsu Semiconductor provides sample programs free of charge to operate the peripheral
resources of the New 8FX family of microcontrollers. Feel free to use such sample programs to
check the operational specifications and usages of Fujitsu microcontrollers.
Note that sample programs are subject to change without notice. As these pieces of software
are offered to show standard operations and usages, evaluate them sufficiently before use with
your system. Fujitsu Semiconductor assumes no liability for any damages whatsoever arising
out of the use of sample programs.

How to Use This Manual
■Finding a Function
The following methods can be used to search for details of a function in this manual:
• Searching from CONTENTS
CONTENTS lists the contents in this manual in the order of description.
• Searching from registers
The address at which a register is located is not mentioned in this manual. To check the
address of a register, refer to "■I/O MAP" in the device data sheet.
■Chapters This manual explains one peripheral function in one chapter.
■Terminology
This manual uses the following terminology.
■NotationsThe notations in "■Register Configuration" in this manual are explained below:
• bit: bit number
• Field: bit field name
• Attribute: Attributes for read access and write access of each bit
- R: Read-only
- W: Write-only
- R/W: Readable/Writable
- —: Undefined
• Initial value: Initial value of a bit after a reset
- 0: The initial value is "0".
- 1: The initial value is "1".
- X: The initial value is undefined.
Multiple bits are indicated in this manual in the following way.
- Example 1: bit7:0 represents bit7 to bit0.
- Example 2: SCM[2:0] represents SCM2 to SCM0.
The values such as those indicating addresses are written in this manual in the following ways:
- Hexadecimal number: The prefix "0x" is attached to the beginning of a value
(e.g.: 0xFFFF).
- Binary number: The prefix "0b" is attached to the beginning of a value (e.g.: 0b1111).
- Decimal number: Only the number is used (e.g.: 1234).
In this manual, "n" in a pin name and a register abbreviation represents the channel number.
Term Explanation
Word Indicates an access in unit of 16 bits.
Byte Indicates an access in unit of 8 bits.

Corrected the connection between the main CR PLL clock
oscillator circuit and the PLLC control register (PLLC).
63 CHAPTER 4 RESET
4.1Reset Operation
■Reset Sources
●Low-voltage detection reset
(optional)
Added the following statement.
However, the LVD reset voltage selection ID register (LVDR)
of the low-voltage detection reset circuit is not reset by the
low-voltage detection reset.
67 4.2.1 Reset Source Register
(RSRR)
■Register Functions
Revised the following statement in details of the EXTS bit.
This bit reads "0" when read by a read access. A write access
(writing "0" or "1") to this bit sets it to "0".
→
A read access or a write access (writing "0" or "1") to this bit
sets it to "0".
Revised the following statement in details of the WDTR bit.
This bit reads "0" when read by a read access. A write access
(writing "0" or "1") to this bit sets it to "0".
→
A read access or a write access (writing "0" or "1") to this bit
sets it to "0".
Revised the following statement in details of the PONR bit.
This bit reads "0" when read by a read access. A write access
(writing "0" or "1") to this bit sets it to "0".
→
A read access or a write access (writing "0" or "1") to this bit
sets it to "0".
68 Revised the following statement in details of the HWR bit.
This bit reads "0" when read by a read access. A write access
(writing "0" or "1") to this bit sets it to "0".
→
A read access or a write access (writing "0" or "1") to this bit
sets it to "0".
Revised the following statement in details of the SWR bit.
This bit reads "0" when read by a read access. A write access
(writing "0" or "1") to this bit or a power on-reset sets it to "0".
→
A read access or a write access (writing "0" or "1") to this bit
or a power-on reset sets it to "0".
