H'01: User MAT
An incorrect area specification will produce an address error.
H'11: Sum-check error
H'2A: Address error (the address specified for reading is beyond the range of the MAT)
H'2B: Size error (the specified amount is greater than the size of the MAT,
the last address for reading as calculated from the specified address for the start of reading
and the amount to read is beyond the MAT area, or "0" was specified as the amount to
read)
