- 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:
- Datasheet7544 Group (QzROM version) DatasheetRECOMMENDED
- 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 7544 Group MCU, detailing examples of interfacing with peripheral ICs equipped with CS pins and other MCUs. It covers transmission-only, transmission and reception modes, and connections involving multiple ICs. The document emphasizes using N-channel open-drain outputs for TxD pins and high-impedance outputs for peripheral ICs during data reception. It also illustrates clock synchronous serial I/O modes with internal and external clock selections and the use of SRDY signal output in UART mode.
- 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:
- Application NoteAI-generated Summary: Renesas Starter Kits (RSK) provide complete development systems including an evaluation board, On Chip Debugger, and peripheral sample code as a Hi-performance Embedded Workshop (HEW) workspace. Users copy the workspace to their PC, open it via HEW, and select the desired project containing source files for specific peripherals. Each project includes a main C source file with detailed comments explaining its functionality, such as ADC single operation mode. Support and additional resources are available on Renesas’ website.Related Files:
- Application NoteAI-generated Summary: The document explains the clock generation circuit operation during power failures for the 7544 Group MCU. It details switching from high-speed main clock to a low-power on-chip oscillator mode when power failure is detected, stopping the main clock oscillation. The system uses wait mode and timer interrupts every 30 ms to check power recovery conditions. Upon recovery, the main clock restarts and switches back to high-speed mode after stabilization. Relevant CPU mode register settings and mode transition procedures are also described.Related Files:
- Application NoteAI-generated Summary: The 7544 Group MCU supports two power-saving modes: stop mode and wait mode. In stop mode, executing the STP instruction halts the main clock, CPU, and peripherals, significantly reducing power consumption. I/O ports maintain their states, and timers and serial I/O stop except under specific conditions. Exiting stop mode requires an enabled interrupt or reset, with a stabilization period for oscillation before normal operation resumes. Proper configuration of watchdog timers and external pin states further optimizes power savings.
- 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.
