Not affected.
The instruction accumulates status as it accesses successive table entries. When the
instruction specifies an address translation cache search with an address register
operand, the MC68030 takes an F-line unimplemented instruction exception.
If there is a parameter specification for a translation table search, the physical address
of the last descriptor successfully fetched loads into the address register. A success-
fully fetched descriptor occurs only if all portions of the descriptor can be read by the
MC68030 without abnormal termination of the bus cycle. If the root pointer’s DT field
indicates page descriptor, the returned address is $0. For a long descriptor, the
address of the first long word is returned. The size of the descriptor (short or long) is
not returned and must be determined from a knowledge of the translation table.
