The main memory is designed for byte-by-byte erasure and writing, providing flexible data management.By writing the corresponding protection bit in the protection memory, the first 32 bytes of memory can be irreversibly protected from data changes. Each protection bit is linked to its respective data byte in the main memory. Once written, the protection bit cannot be erased, ensuring secure and permanent data protection (PROM functionality).
