SH7125_08 Datasheet, PDF (6/774 Pages) Renesas Technology Corp – Renesas 32-Bit RISC Microcomputer SuperH™ RISC engine Family

Preface
The SH7125 Group and SH7124 Group RISC (Reduced Instruction Set Computer) microcomputer
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 be using the SH7125 Group and
SH7124 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 SH7125 Group and SH7124 Group 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
Read the index that is the final part of the manual to find the page number of the entry on the
register. The addresses, bits, and initial values of the registers are summarized in section 20,
List of Registers.
Examples: Register name: The following notation is used for cases when the same or a
similar function, e.g. 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
