- 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: The document explains serial I/O connections for the 7548/7549 MCU group, detailing examples of interfacing with peripheral ICs equipped with CS pins and connections between multiple ICs or MCUs. It covers clock synchronous serial I/O modes using internal or external clocks and highlights the use of N-channel open-drain outputs for TxD pins and peripheral IC outputs for data reception. The document also describes the SRDY signal function in clock synchronous mode and UART mode connections.
- Application NotePDF 187 KB REJ05B1097-0100 Rev.1.00 Sep 18, 2008AI-generated Summary: The oscillation stop detection function monitors the XIN oscillator in the 7548 and 7549 MCU groups using a ceramic resonator as the main clock. It triggers a reset when oscillation stops, ensuring system stability. After reset, the system verifies XIN oscillation before starting the main process. The function uses specific register settings to activate detection, enable reset, and confirm oscillation status. A watchdog timer supports system reliability. The document details register configurations and control procedures for implementing this function.Related Files:
- Application NoteAI-generated Summary: The oscillation stop detection function monitors the main clock oscillation in the 7542 Group MCU using a ceramic resonator. It triggers a reset when oscillation stops and retains the detection status bit until cleared. The system confirms clock oscillation before starting the main process and disables the watchdog timer. Relevant register settings and control procedures manage the detection and reset functions, ensuring stable clock operation and appropriate countermeasures if oscillation fails.Related Files:
- Application NoteAI-generated Summary: The document explains the process of rewriting the program ROM using EWO mode for the R8C/2D Group MCU. It details transferring the CPU rewrite program to RAM, enabling CPU rewrite mode, and executing program and erase commands while allowing interrupts during programming. The flowchart outlines setting the system clock, transferring the rewrite program, executing block erase and program commands, reading the array, and disabling rewrite mode before returning to the main process.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: Renesas Starter Kit sample code is provided as a Hi-performance Embedded Workshop (HEW) workspace, including peripheral sample projects for the SH7124 microcontroller. Users copy the workspace to their PC, open it via HEW, and select the desired project to access source files. Each project demonstrates peripheral initialization with C source files containing main functions and detailed comment blocks explaining functionality. Example code sets up ADC Channel 0 for single operation mode with software trigger. Support and inquiries are available via Renesas websites.Related Files:
