描述
The R8C/18 Group is supported only for customers who have already adopted these products. The RL78/G12 Group is recommended for new designs.
This MCU is built using the high-performance silicon gate CMOS process using the R8C/Tiny Series CPU core and is packaged in a 20-pin plastic molded LSSOP. This MCU operates using sophisticated instructions featuring a high level of instruction efficiency. With 1Mb of address space, it is capable of executing instructions at high speed. Furthermore, the data flash ROM (1KB × 2 blocks) is embedded in the R8C/17 group. The difference between the R8C/16 and R8C/17 groups is only the existence of the data flash ROM. Their peripheral functions are the same.

- 应用说明英语AI 生成的摘要: 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.

It details boot program operations including initial settings, communication with a serial programmer, and control commands for flash memory. Communication formats are asynchronous, with defined data transfer structures. Pin assignments and connection examples for both modes are provided. Initial settings cover selecting communication mode based on the MODE pin level after reset and adjusting the bit rate to 9600 bps through a defined handshake process with the serial programmer.

- 应用说明英语PDF 126 KB R20AN0090ES0100 Rev.1.00 2010年3月01日AI 生成的摘要: 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.
- 应用说明英语PDF 938 KB R20AN0089ES0100 Rev.1.00 2010年3月01日AI 生成的摘要: 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.
- 应用说明英语PDF 695 KB R20AN0088ES0100 Rev.1.00 2010年3月01日AI 生成的摘要: Interrupts enable embedded systems to handle time-critical tasks by signaling the processor to pause current operations and address urgent events. There are hardware and software interrupts, with hardware interrupts further divided into special and peripheral I/O types. The R8C family uses two interrupt vector tables: fixed and relocatable, which store interrupt service routines and their properties. Interrupt priority levels allow nested interrupts, and interrupts can be maskable or non-maskable, with NMIs reserved for critical system events.查看更多 (88)
