H8/38124

AI-generated Summary: The guide details the migration process from the H8/3048 microcontroller to the RX231, highlighting key differences in CPU architecture, system registers, and peripheral modules. It explains the expanded general-purpose registers in RX231, differences in stack pointer usage, and changes in interrupt handling, clock settings, and operating modes. The document also compares on-chip functions such as I/O ports, buses, DMA controllers, timers, and converters, providing essential information for smooth hardware and software transition.

AI-generated Summary: The document explains how to register and uninstall Call Walker within the High-performance Embedded Workshop (HEW). It guides users to launch HEW without opening a workspace, access the Tools Administration menu, and register the Call Walker tool by specifying the registration file path. After registration, Call Walker version 2.3 appears in the menu. Upon uninstalling HEW, users must manually delete the remaining Call Walker directory. It also provides Renesas Electronics website and contact information for support. The revision history notes the first edition release date.

AI-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.

AI-generated Summary: Call Walker is a stack information analysis tool included in the Renesas Compiler Package for various microcontroller families. It reads stack information files (*.sni) generated by the linkage editor or profile information files (*.pro) from the simulator debugger. Users can edit stack sizes, save modified data in call information files (*.cal), and merge multiple files. Procedures to create stack information files differ by microcontroller family, with specific instructions for SuperH, H8, RX, M16C, and R8C families. The tool supports static stack size display and editing for assembly programs.

AI-generated Summary: The document provides example C code for initializing and configuring the RTC and LCD controller of the H8/38076F microcontroller. It details the hardware description, focusing on the RTC's functionality, registers, and initialization procedure. The RTC counts time from seconds to a week, supports BCD-coded read/write, and generates interrupts. It also explains the importance of checking the BSY bit during register updates to ensure accurate data reading.

AI-generated Summary: This document provides example C code for initializing and configuring Timer A, the LCD controller, and implementing an IIC interface using a standard IO port on the H8/38024F microcontroller. It includes code to generate interrupts every second, control a 7-segment LCD display, create a software real-time clock, and communicate with external EEPROM and RTC devices via software IIC. The development environment setup and device block diagram are also detailed.
