MPU Memory Maps
3.2.1 MPU Global Memory Map
The MPU has a unified address space; therefore, the internal and external memories for program and data,
as well as peripheral registers and configuration registers, are all accessed within the same address space.
The MPU space is always addressed using byte addressing. Table 31 provides a high level illustration of the
entire MPU addressable space. Table 32 shows the chip-select mapping. More details about the peripheral
and configuration registers are provided in Section 3.2.2, MPU Subsystem Registers Memory Map.
