Overview
Description
The RA8E1 Fast Prototyping Board comes equipped with an R7FA8E1AFDCFB microcontroller and is an evaluation board specialized for prototype development for a variety of applications. It has a built-in SEGGER J-Link™ emulator circuit so you can write and debug programs without additional tools. In addition, with Arduino® UNO and Pmod™ interfaces included standard and through-hole access to all pins of the microcontroller, and so on, it has high expandability.
Sample software is available to demonstrate the functionality of the RA8E1 MCU and for connecting the RA8E1 Fast Prototyping Board with various wireless or sensor modules.

Configure and use the Watchdog Timer (WDT) and Independent Watchdog Timer (IWDT) on RA devices with the RA8E1 fast prototyping board. Project setup using the Flexible Software Package in e² studio is included, along with separate implementations for WDT and IWDT. Countdown behavior is displayed using SEGGER RTT to indicate timing before reset. Normal operation with watchdog expiration and system restart is shown for WDT. Fault-triggered reset behavior is demonstrated using IWDT to illustrate its role in system recovery.
