H8/38702S

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: Guidelines for designing Hi-Speed USB 2.0 boards focus on the SH7263/SH7203 devices, detailing pin functions and USB transmission line requirements. The USB 2.0 transmission lines require controlled differential impedance of 90 Ω ± 15%, with specific wiring lengths to meet USB specifications. The design emphasizes ground planes, separation from noisy signals, uniform spacing, and gentle bends in wiring to maintain signal integrity. Power supply and grounding details for transceiver pins are also outlined.

AI-generated Summary: The document explains how to use the Timer RG and port output to operate a programmable timing pattern controller (TPC) in H8S/20103, H8S/20203, and H8S/20223 groups. It details setting the compare match A signal from Timer RG as a time base for pulse output without CPU intervention, using event link controller (ELC) to link timer signals to port outputs. The setup includes configuring timer modes, data transfer controller (DTC) for repeated data transfer from ROM to output ports, and enabling event linkage and interrupts to automate pulse output on port pins P30 to P34.

AI-generated Summary: A Perl script converts S-record data into a C structure, enabling flash programming routines where code runs from RAM but is stored in flash memory. Unlike the Win32 utility 'motice_cl', this script offers cross-platform compatibility and customizable output formatting. It runs on Windows and Linux with Perl implementations and integrates into the Renesas HEW IDE as a build phase. The script generates a C structure with start address, data length, and data array fields, adaptable to the input S-record size.

AI-generated Summary: Renesas SH and H8 Flash microcontrollers support self-programming via a built-in bootloader called boot mode, which programs devices through a specified serial channel. User boot mode allows running a custom bootloader from a separate 8kB Flash section mapped at address zero, simplifying custom Flash programming. This note demonstrates implementing a serial Flash bootloader using the Xmodem protocol on H8/3069F and SH7058F devices, with source code available. The bootloader operates via SCI channel 1 at 57600 baud, providing menu options for erasing and programming Flash memory.
