RX Family, SH Family, H8SX Family Points of Difference between RCAN-ET (SH Family, H8SXFamily) and CAN (RX Family) Rev.1.00
PDF 361 KB R01AN4767EJ0100 Rev.1.00 日本語 Sep 30, 2019
AI-generated Summary: The document details functional differences between RCAN-ET (SH and H8SX Families) and CAN (RX Family) controllers. It compares protocol compatibility, bit rates, channel numbers, mailbox configurations, ID formats, and transmission/reception capabilities. Key distinctions include FIFO mailbox support, message priority handling, interrupt types, error handling, and bus-off recovery. The RX65N supports more channels, FIFO modes, and additional interrupts, while SH7137 offers ID reordering and overwrite modes. These differences impact CAN communication performance and error management.

RX Development Environment Migration Guide Migration from SuperH Family to RX Family (IDE ed.) (High-performance Embedded Workshop to CS+)
PDF 1007 KB REJ06J0102-0200 Rev.2.00 日本語 Apr 20, 2017
AI-generated Summary: The document explains key compiler option differences when migrating source code from the SuperH family to the RX family. It highlights that char types default to signed in SuperH but unsigned in RX, requiring the 'signed_char' option to maintain behavior. It also covers the 'auto_enum' option for automatic enum size selection and the 'dbl_size' option to specify double type size, which defaults to 4 bytes in RX compared to 8 bytes in H8 compilers. Configuration steps in the CS+ IDE are provided for each option.

Compiler Package Application Note: The application guide of Call Walker Rev.1.00
PDF 243 KB R20AN0294EJ0100 Rev.1.00 日本語 Feb 18, 2014
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.

SH-2, SH-2A Fixed-point Library (Ver. 1.02)
PDF 242 KB R01AN1355EJ0102 Rev.1.02 日本語 Sep 11, 2012
AI-generated Summary: The SH-2 and SH-2A Fixed-point Library (Ver. 1.02) provides fixed-point arithmetic functions through the 'fixmath.h' header and corresponding libraries (sh2fix.lib, sh2afix.lib). It supports fixed-point operations like conversion between float and fixed-point types and trigonometric calculations. Usage instructions include copying files to local directories and specifying libraries in the High-Performance Embedded-Workshop environment. The library warns that results exceeding fixed-point range are not guaranteed. The 'fixmath.h' file defines types and macros for fixed-point operations, with function names indicating bit widths.
