Preface

The H8SX/1663 Group is a single-chip microcomputer made up of the high-speed internal 32-bit

H8SX CPU as its core, and the peripheral functions required to configure a system. The H8SX

CPU is upward compatible with the H8/300, H8/300H, and H8S CPUs.

Target Users:

This manual was written for users who will be using the H8SX/1663 Group in the

design of application systems. Target users are expected to understand the

fundamentals of electrical circuits, logical circuits, and microcomputers.

Objective:

This manual was written to explain the hardware functions and electrical

characteristics of the H8SX/1663 Group to the target users.

Refer to the H8SX Family Software Manual for a detailed description of the

instruction set.

Notes on reading this manual:

• In order to understand the overall functions of the chip

Read the manual according to the contents. This manual can be roughly categorized into parts

on the CPU, system control functions, peripheral functions and electrical characteristics.

• In order to understand the details of the CPU's functions

Read the H8SX Family Software Manual.

• In order to understand the details of a register when its name is known

Read the index that is the final part of the manual to find the page number of the entry on the

List of Registers.

Examples:

The following notation is used for cases when the same or a

similar function, e.g. 16-bit timer pulse unit or serial

communication interface, is implemented on more than one

channel:

XXX_N (XXX is the register name and N is the channel

number)

Bit order:

The MSB is on the left and the LSB is on the right.

Number notation:

Binary is B'xxxx, hexadecimal is H'xxxx, decimal is xxxx.

Signal notation:

An overbar is added to a low-active signal:

xxxx
