Description
The SH7144 Series single-chip RISC (Reduced Instruction Set Computer) microcomputers integrate a Renesas-original RISC CPU core with peripheral functions required for system configuration. The SH7144 series CPU has a RISC-type instruction set. Most instructions can be executed in one state (one system clock cycle), which greatly improves instruction execution speed. With this CPU, it has become possible to assemble low cost, high performance/high-functioning systems, even for applications that were previously impossible with microcomputers, such as real-time control, which demands high speeds. & In addition, the SH7144 series includes on-chip peripheral functions necessary for system configuration, such as a direct memory access controller (DMAC), large-capacity ROM and RAM, timers, a serial communication interface (SCI), an A/D converter. ROM and SRAM can be directly connected to the SH7144 MCU by means of an external memory access support function. This greatly reduces system cost.

- Application NoteAI-generated Summary: The document details the Renesas CAN Controller's usage, including compatibility, evaluation results, and principles of pretended networking. It covers sample software descriptions, CAN driver functionalities such as initialization, configuration, transmission, reception, and diagnostics. The text also explains mapping of lower CAN drivers, application examples, and frequently asked questions addressing CAN conformance, transceiver issues, bit timing, operation modes, power save modes, transmission, reception, message storage, peripheral bus access, and interrupt handling.

- Application NoteAI-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.

- Application NoteAI-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.

- Application NoteAI-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.Related Files:

SH Family: What is the difference between the DTC and DMAC?
The DMAC(Direct Memory Access Controller) has registers dedicated to each channel to designate a transfer address, mode and so on. Contrary to this, the DTC(Data Transfer Controller) stores data such as a transfer address, mode in the memory, and once transfer is requested, it reads these data and ...
