Texas Instruments TM4C1294NCPDT User Manual

Register 72: MPU Region Base Address (MPUBASE), offset 0xD9C
Register 73: MPU Region Base Address Alias 1 (MPUBASE1), offset 0xDA4
Register 74: MPU Region Base Address Alias 2 (MPUBASE2), offset 0xDAC
Register 75: MPU Region Base Address Alias 3 (MPUBASE3), offset 0xDB4
Note: This register can only be accessed from privileged mode.
The MPUBASE register defines the base address of the MPU region selected by the MPU Region
Number (MPUNUMBER) register and can update the value of the MPUNUMBER register. To
change the current region number and update the MPUNUMBER register, write the MPUBASE
register with the VALID bit set.
The ADDR field is bits 31:N of the MPUBASE register. Bits (N-1):5 are reserved. The region size,
as specified by the SIZE field in the MPU Region Attribute and Size (MPUATTR) register, defines
the value of N where:
N = Log
2
(Region size in bytes)
If the region size is configured to 4 GB in the MPUATTR register, there is no valid ADDR field. In
this case, the region occupies the complete memory map, and the base address is 0x0000.0000.
The base address is aligned to the size of the region. For example, a 64-KB region must be aligned
on a multiple of 64 KB, for example, at 0x0001.0000 or 0x0002.0000.

Bits 31:N in this field contain the region base address. The value of N
depends on the region size, as shown above. The remaining bits (N-1):5
are reserved.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
