Configurable Fault Status Registers
IACCVIOL | 0 (VALUE_0): no instruction access violation fault 1 (VALUE_1): the processor attempted an instruction fetch from a location that does not permit execution |
DACCVIOL | 0 (VALUE_0): no data access violation fault 1 (VALUE_1): the processor attempted a load or store at a location that does not permit the operation |
MUNSTKERR | 0 (VALUE_0): no unstacking fault 1 (VALUE_1): unstack for an exception return has caused one or more access violations |
MSTKERR | 0 (VALUE_0): no stacking fault 1 (VALUE_1): stacking for an exception entry has caused one or more access violations |
MLSPERR | 0 (VALUE_0): No MemManage fault occurred during floating-point lazy state preservation 1 (VALUE_1): A MemManage fault occurred during floating-point lazy state preservation |
MMARVALID | 0 (VALUE_0): value in MMAR is not a valid fault address 1 (VALUE_1): MMAR holds a valid fault address |
IBUSERR | 0 (VALUE_0): no instruction bus error 1 (VALUE_1): instruction bus error |
PRECISERR | 0 (VALUE_0): no precise data bus error 1 (VALUE_1): a data bus error has occurred, and the PC value stacked for the exception return points to the instruction that caused the fault |
IMPRECISERR | 0 (VALUE_0): no imprecise data bus error 1 (VALUE_1): a data bus error has occurred, but the return address in the stack frame is not related to the instruction that caused the error |
UNSTKERR | 0 (VALUE_0): no unstacking fault 1 (VALUE_1): unstack for an exception return has caused one or more BusFaults |
STKERR | 0 (VALUE_0): no stacking fault 1 (VALUE_1): stacking for an exception entry has caused one or more BusFaults |
LSPERR | 0 (VALUE_0): No bus fault occurred during floating-point lazy state preservation 1 (VALUE_1): A bus fault occurred during floating-point lazy state preservation |
BFARVALID | 0 (VALUE_0): value in BFAR is not a valid fault address 1 (VALUE_1): BFAR holds a valid fault address |
UNDEFINSTR | 0 (VALUE_0): no undefined instruction UsageFault 1 (VALUE_1): the processor has attempted to execute an undefined instruction |
INVSTATE | 0 (VALUE_0): no invalid state UsageFault 1 (VALUE_1): the processor has attempted to execute an instruction that makes illegal use of the EPSR |
INVPC | 0 (VALUE_0): no invalid PC load UsageFault 1 (VALUE_1): the processor has attempted an illegal load of EXC_RETURN to the PC |
NOCP | 0 (VALUE_0): no UsageFault caused by attempting to access a coprocessor 1 (VALUE_1): the processor has attempted to access a coprocessor |
UNALIGNED | 0 (VALUE_0): no unaligned access fault, or unaligned access trapping not enabled 1 (VALUE_1): the processor has made an unaligned memory access |
DIVBYZERO | 0 (VALUE_0): no divide by zero fault, or divide by zero trapping not enabled 1 (VALUE_1): the processor has executed an SDIV or UDIV instruction with a divisor of 0 |
