0 No local bus parity error
1 Local bus parity error. LTEATR[PB] indicates the byte lane that caused the error and LTEATR[BNK]
Reserved
Write protect error
0 No write protect error occurred.
1 A write was attempted to a local bus memory region that was defined as read-only in the memory controller.
Reserved
0 No atomic write error occurred.
1 The subsequent write (WARA) to a memory bank did not occur within 256 bus clock cycles.
0 No atomic read error occurred.
1 The subsequent read (RAWA) to a memory bank did not occur within 256 bus clock cycles.

indicates which memory controller bank was accessed.
Usually, in this case, a bus monitor time-out will occur (as the cycle is not automatically terminated).
