- Application NoteAI-generated Summary: The document explains the operation of three-phase motor control timers in sawtooth wave modulation mode for M32C/84, 85, 87, 88, 8A, and 8B groups. It details how the IDBO and IDB1 registers determine individual phase output signal levels, with signals output at specific timer edges. Dead time between switching signals is configurable via the DTT register and controlled by the INV14 bit in the INVC1 register. Examples of default PWM register values and signal timing diagrams illustrate the modulation and output process.Related Files:
- Application NoteAI-generated Summary: The document demonstrates the use of the H8S/38076 microcontroller's real-time clock (RTC) and LCD peripherals across seven power modes. It includes system and peripheral overviews, detailed register descriptions for RTC and LCD controllers, and software functions for initialization, power mode setting, and LCD updating. The document also covers interrupt service routines, current consumption measurement techniques, memory allocation, and code structure.Related Files:

- Application NoteAI-generated Summary: Ensure safety in circuit designs by considering potential semiconductor failures that may cause injury, fire, or damage. Use auxiliary circuits, non-flammable materials, and malfunction prevention. Product information may change without notice, and Renesas disclaims liability for damages from inaccuracies. Semiconductors are not for life-critical systems without prior approval. The document explains C language programming basics, project setup, compiler, assembler, linker, debugger, coding tips, stack estimation, and interrupt handling for the Renesas 740 family microcomputers.
- Application NoteAI-generated Summary: This document explains how to design PCB layouts to enhance noise immunity for the 740 family MCU, using the M37544G2ASP sample at 4 MHz on a single-sided board. It compares recommended and non-recommended layouts, highlighting five key design points: short oscillator wiring, close reset circuit placement, short CNVSS wiring with a resistor, decoupling capacitor placement near MCU, and unified VSS wiring. These principles reduce noise-induced failures and improve MCU stability.

- Application NotePDF 109 KB REJ05B0821-0101 Rev.1.01 May 18, 2006AI-generated Summary: The document compares the 3826A Group and 7560A Group microcontrollers, highlighting differences in target devices, memory types, oscillation circuit constants, hysteresis characteristics, sub-clock oscillation circuits, and power pin handling. The 3826A Group includes DTMF and CTCSS functions absent in the 7560A Group. It is pin-compatible with the 7560A Group but differs electrically. Recommendations include selecting appropriate oscillation circuits and considering noise reduction. The document also notes emulator MCU differences and programming considerations for unused functions.
- Application NoteAI-generated Summary: The programming guidelines for the 740 Family in C language have been updated and replaced by a new document titled "C Compiler Package for 740 Family M3T-ICC740 Application Notes" (Document No. REJ06J0005-0100). Users should refer to this new document for current information. Inquiries related to the previous guidelines should be sent via email to the provided contact.
- Application NoteAI-generated Summary: This document explains two methods for handling interrupts in the ICC-740 C Compiler for the 740 Family MCU. Method 1 involves modifying the interrupt vector table in the startup file and declaring interrupt functions with the 'interrupt' keyword. Method 2 deletes the interrupt vector table, reserves data space, and declares interrupt functions using the 'interrupt [offset]' syntax. Examples illustrate how to implement INTO interrupt handling in both methods.
