Chapter 4 Memory Protection Unit (S12XMPUV1)
access is allowed or represents an access violation. If an access violation caused by the S12X CPU is
detected, the MPU module raises an access violation interrupt. If the MPU module detects an access
violation caused by a bus master other than the S12X CPU, it flags an access error condition to the
respective master. In addition to the restrictions defined for memory ranges in the MPU descriptors,
accesses to memory not covered by any MPU descriptor (even read accesses!) are considered access
violations.
