- 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 presents performance data of the signal processing library on SH2A-FPU and RX devices, detailing CPU cycles for various DSP functions such as FFT, FIR, and IIR filters across different sample sizes and coefficients. It also provides Renesas Electronics website and support contact information. The revision record notes the first edition release date as December 17, 2010.Related Files:
- Application NoteAI-generated Summary: The document explains how to convert analog input voltage from a sensor into digital values using the 7546/47 MCU group. It details the connection of the sensor to the P20/AN0 pin and provides step-by-step instructions for setting relevant registers, including disabling interrupts, selecting the analog input pin, setting the A/D control register, and configuring interrupt settings. Notes clarify specific settings for different MCU groups and oscillator types.
- 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: This document explains the operation of Timer A in the M16C/64 group for processing 2-phase pulse signals in event counter mode using normal processing. It details the selection of specific functions, including count operation type, reload type, and output polar control. The timer counts effective edges based on input signals, continues counting through underflow and overflow without reloading, and triggers interrupts accordingly. Timing diagrams illustrate start count, overflow, and underflow events.Related Files:
- Application NoteAI-generated Summary: Renesas Starter Kits provide complete development systems including evaluation boards, debuggers, and peripheral sample code as HEW workspaces. Users copy the workspace to their PC, open it via HEW, and select specific sample projects to access source files. Each project demonstrates peripheral initialization with C source files containing main functions and descriptive comment blocks. Sample code guides users through building, downloading, and debugging processes. Support and inquiries are available through Renesas’ website.Related Files:

- Application NoteAI-generated Summary: This document details the differences between the 7546/47 Group and the 7544 Group (QZROM version) microcontrollers. It compares product models, package types, ROM/RAM sizes, I/O ports, interrupts, timers, serial interfaces, A/D converters, and built-in circuits such as watchdog timers and power-on reset. It also outlines pin configurations and memory maps, highlighting variations in function set ROM areas and features like oscillator modes and watchdog timer operations.
- Application NotePDF 761 KB REC05B0025-0102 Rev.1.02 Mar 21, 2008AI-generated Summary: This document explains how to generate PWM waveforms using the Output Compare Function of Timer A in the 7546/7547 MCU groups. It details the initialization of timer registers, the timing of PWM output, and formulas for calculating PWM period and duty cycle. The document also describes setting up output compare channels, focusing on channel 0, and configuring related registers for port direction, interrupts, timer mode, count source, and timer values.Related Files:
