• IREGION
Indicates the number of supported MPU instruction regions.
Always contains 0x00. The MPU memory map is unified and is described by the DREGION field.
• DREGION
Indicates the number of supported MPU data regions:
0x08 = Eight MPU regions.
• SEPARATE
Indicates support for unified or separate instruction and date memory maps:
0 = unified.
