Preface

The SH7618 Group RISC (Reduced Instruction Set Computer) microcomputers include a Renesas

Technology-original RISC CPU as its core, and the peripheral functions required to configure a

system.

Target Users:

This manual was written for users who will use the SH7618 and SH7618A 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 SH7618 and SH7618A to the target users.

Refer to the SH-1/SH-2/SH-DSP 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 SH-1/SH-2/SH-DSP Software Manual.

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

• The addresses, bits, and initial values of the registers are summarized in section 20, 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
