U, \6 w) ?5 s7 G( p' t 0 = no instruction access violation fault, l O y6 ^) H 1 = the processor attempted an instruction fetch from a location that does not permit execution. The PC value stacked for the exception return points to the faulting instruction. The processor has not written a fault address to the MMAR. This fault condition occurs on any access to an XN (eXecute Never) region, even when the MPU is disabled or not present. Potential reasons: a) Branch to regions that are not defined in the MPU or defined as non-executable. b) Invalid return due to corrupted stack content. c) Incorrect entry in the exception vector table
