Flash memory interface

2.1

Introduction

The Flash memory interface manages CPU AHB I-Code and D-Code accesses to the

1 Mbyte (64 Kbit × 128 bits) Flash memory. It implements the erase and program Flash

memory operations and the read and write protection mechanisms.

The Flash memory interface accelerates code execution with a system of instruction

prefetch and cache lines.
