- 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: This document explains how to configure and operate the asynchronous serial interface mode (UART) for data reception at 9600bps using the R32C/100 Series MCUs. It details setting bit rates, data format (8-bit length, odd parity, 1 stop bit), and internal clock usage. RTS pins control data reception flow, with specific port and register settings provided. The reception process includes RTS signaling, bit order, and interrupt handling upon data receipt.Related Files:
- Application NotePDF 126 KB R20AN0090ES0100 Rev.1.00 Mar 01, 2010AI-generated Summary: The system timer in MR8C/4 tracks elapsed time in an RTOS by generating periodic interrupts, incrementing a tick counter. The timer's resolution depends on application needs, hardware limitations, and counter storage. MR8C/4 uses a 6-byte counter allowing up to 8925 years of tick counting at 1ms resolution. Hardware timer inaccuracies require adjustments to ensure minimum delay durations. Users configure the system timer by selecting hardware timers, setting interrupt priorities, and defining interrupt vectors. The system timer manages time-based functions and is optional if no time management is used.
- Application NotePDF 938 KB R20AN0089ES0100 Rev.1.00 Mar 01, 2010AI-generated Summary: MR8C/4 provides two types of time event handlers: cyclic handlers for repetitive events at fixed intervals, and alarm handlers for one-shot events at specified times. These handlers operate independently from tasks, executing in non-task contexts with priority between interrupts and dispatchers. Time event handlers must be statically created in configuration files and require the CPU to be unlocked for activation. Accuracy depends on system timer resolution, with R8C devices supporting up to 1 ms resolution. Cyclic handlers can be used to trigger tasks periodically without reprogramming timers.View More (103)

Do I need to rewrite the boot ROM area using MI6C Flash Starter?
Rewriting of the boot ROM area is unnecessary. This is because M3A-0806 performs programming using the standard boot program which was programmed into the boot ROM area when it was shipped. (#104963)
