[−] Expand description

MemManage Fault Address Register.

Fields

address: Address<_T>

[−] Expand description

Data address for an MPU fault. This is the location addressed by an attempted load or store access that was faulted. The MemManage Status Register shows the cause of the fault, and whether MMFAR.ADDRESS is valid. When an unaligned access faults, the address is the actual address that faulted. Because an access might be split into multiple parts, each aligned, this address can be any offset in the range of the requested size.
