Memory organization

2.2.1

Introduction

Program memory, data memory, registers and I/O ports are organized within the same linear
4-Gbyte address space.
The bytes are coded in memory in Little Endian format. The lowest numbered byte in a word
is considered the word's least significant byte and the highest numbered byte the most
significant.
The addressable memory space is divided into eight main blocks, of 512 Mbytes each.
The access to some part of the address space is master dependent, see
and bus architecture for details.
