Memory, Register Mapping, and Access
3.1
Overview
The Arm Cortex-M4 with FPU core defines a standard memory space for unified code and data access. This memory space is
addressed in units of single bytes but is most typically accessed in 32-bit (4 byte) units. It may also be accessed, depending
on the implementation, in 8-bit (1 byte) or 16-bit (2 byte) widths. The total range of the memory space is 32-bits in width
(4GB addressable total), from addresses 0x0000 0000 to 0xFFFF FFFF.
It is important to note, however, that the architectural definition does not require the entire 4GB memory range to be
populated with addressable memory instances.
