H8/3052B

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: The M3S-T2-Tiny is an ultracompact TCP/IP protocol stack software library designed for R8C Family, H8/300H Tiny Series, H8/300H Series, and M16C/Tiny Series microcontrollers. It supports Ethernet and PPP data link layers and includes TCP, UDP, IP, ICMP, ARP, and PPP protocols. The library separates hardware-dependent drivers for LAN controllers or serial I/O, providing sample drivers and applications. It uses an API compliant with ITRON TCP/IP standards and does not require a real-time OS. The package contains library files, header files, configuration templates, sample drivers, and sample application programs.

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.

AI-generated Summary: Renesas Flash microcontrollers support three programming modes: PROM, boot, and user. PROM mode uses an external programmer with high speed but limited field use. Boot mode allows in-circuit programming by downloading routines into internal RAM, erasing Flash memory each time. The 0.18µm devices add a user boot mode, enabling a programmable bootloader area. User mode offers flexible in-field reprogramming by running routines from RAM or external memory, supporting partial erasing and various data interfaces. Flash memory must not be accessed during erase/program operations, requiring code execution from RAM or external memory with interrupts disabled.
