Description: When the problem occurs, 8 bytes of incorrect data is written to the 8-byte boundary
that includes an address that differs by H'2000 from the address accessed by the store instruction
that accesses internal RAM mentioned in condition 4. For example, when a long word is stored at
address H'7C000204, the 8 bytes of data in the internal RAM mapped to addresses H'7C002200 to
H'7C002207 becomes corrupted.

STS.L) that accesses internal RAM (H'7C000000 to H'7FFFFFFF) exists within four
instructions after the instruction associated with the exception or interrupt described
in condition 3. This includes cases where the store instruction that accesses internal
RAM itself generates an exception.
R0 is an address causing a TLB miss.
R1 is an address mapped to internal RAM.
TLB miss exception occurs.
