M16C/63, 64A, 64C, 65, 65C, 6C, 5LD, 56D, 5L, 56,5M, and 57 Groups Troubleshooting for Serial Communications in Development
PDF 903 KB R01AN1622EJ0120 Rev.1.20 日本語 Dec 15, 2017
AI-generated Summary: This document provides detailed troubleshooting guidance for serial communications in M16C/63, 64A, 64C, 65, 65C, 6C, 5LD, 56D, 5L, 56, 5M, and 57 groups during development. It covers issues in clock synchronous and asynchronous serial I/O modes, including transmit data not outputting, unexpected data, missing data, reception errors, overrun errors, and communication errors. It also explains causes such as disabled transmission, CTS function settings, pin configurations, and clock signal problems, along with analysis methods like register checking and signal examination.

PDF 990 KB R01AN1895EJ0110 Rev.1.10 日本語 Dec 01, 2014
AI-generated Summary: The document addresses troubleshooting issues in the I2C mode of serial interfaces for various M16C groups. It details common problems such as unexpected interrupts, fast-mode communication failures, bit slippage, and overrun errors. Solutions include verifying interrupt request bits, proper interrupt source switching procedures, and checking digital delay values and register settings. The document also provides application notes and debugging methods to identify interrupt-related issues.

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.

PDF 730 KB R01AN1350EJ0110 Rev.1.10 日本語 Dec 02, 2013
AI-generated Summary: This document provides detailed troubleshooting guidance for clock-related issues in specific MCU groups during development. It covers problems such as CPU clock switching failures, clock oscillation stops, program malfunctions, unexpected resets, and interrupts. The guide explains causes like disabled write operations to protected registers, improper clock settings, and unstable oscillations. It also includes methods for analyzing register settings, clock frequencies, and system behavior to identify and resolve issues effectively.

M16C/50 Series CAN Application Note
PDF 360 KB R01AN1649EJ0100 Rev.1.00 Mar 31, 2013
AI-generated Summary: The document details the initial settings required for CAN communication, focusing on CAN bit timing for the M16C/50 Series. It explains the structure of each bit in the communication frame, composed of synchronization segment (SS), time segment 1 (TSEG1), and time segment 2 (TSEG2). Adjusting TSEG1 and TSEG2 changes the sampling point timing. The timing unit is time quanta (Tq), influenced by clock frequency and baud rate prescaler. It specifies valid ranges and restrictions for SS, TSEG1, TSEG2, and resynchronization jump width (SJW) to ensure proper synchronization and phase error compensation during communication.
