Overview
Description
The Flash Access Driver (FAD) provides simple operation as an API (FAD function) to handle flash memory operations by calling the FAD functions within the application. This FAD handles calls of the "Flash Application Command Interface (FACI)" in the flash hardware. It interacts with code flash memory or data flash memory.
- Erasing
- Programming
- Blank checking
- Security settings, etc.

AI-generated Summary:
The Flash Access Driver (FAD) provides a comprehensive API and sample programs for managing embedded code flash and data flash memory on RH850/P1x-C devices. It includes libraries and source files for flash operations such as initialization, programming, erasing, and status management. The driver supports security features like ID authentication, lock bits, and OTP protection. Detailed API functions cover hardware setup, error handling, and flash protection mechanisms. Sample projects demonstrate usage scenarios executed from RAM or code flash. Notes address operational constraints, interrupt handling, and debugging considerations to ensure reliable flash memory control.
