- 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: The document explains how to use Serial I/O 1 and 2 in clock synchronous serial I/O mode on the 38D2 Group MCU with a 4 MHz oscillator. It details transmitting and receiving 2-byte data using a 125 kHz synchronous clock and SRDY signal for communication control. The transmit side uses INT1 interrupt to confirm SRDY and send data, while the receive side outputs SRDY every 2 ms via a timer. It includes connection diagrams, timing charts, register settings, and control procedures for both transmit and receive sides.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 254 KB REJ05B0874-0100 Rev.1.00 Jun 13, 2006AI-generated Summary: The document details the differences between the Renesas 7544 and 7540 Groups, focusing on applicable products, package types, ROM/RAM sizes, instruction execution times, I/O ports, interrupts, timers, serial interfaces, A/D converters, LED ports, power source voltages, and security features. It highlights variations in pin configurations, package availability, and electrical characteristics, providing a comprehensive comparison for design and application considerations.
- 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.
