MPU Descriptor Register 4 (MPUDESC4)
MPU Descriptor Register 5 (MPUDESC5)
No-Execute bit — The NEX bit prevents the described memory range from being used as code memory. If this
bit is set every Op-code fetch in this memory range causes an access violation.
Memory range upper boundary address bits — The HIGH_ADDR[22:19] bits represent bits [22:19] of the
global memory address that is used as the upper boundary for the described memory range.
Memory range upper boundary address bits — The HIGH_ADDR[18:11] bits represent bits [18:11] of the
global memory address that is used as the upper boundary for the described memory range.
Memory range upper boundary address bits — The HIGH_ADDR[10:3] bits represent bits [10:3] of the
global memory address that is used as the upper boundary for the described memory range.
