Supervisor (Privileged) Instructions
MOVES

The value stored is undefined for either of the two following
examples with the same address register as both source and
destination.
The current implementations of the MC68010, MC68020,
MC68030, and MC68040 store the incremented or decremented
value of An. Check the following code sequence to determine
what value is stored for each case.
Because the MC68040 implements a merged instruction and
data space, the MC68040’s integer unit into data references
(SFC/DFC = 5 or 1) translates MOVES accesses to the
OinstructionO address spaces (SFC/DFC = 6 or 2). The data
memory unit handles these translated accesses as normal data
accesses. If the access fails due to an ATC fault or a physical
bus error, the resulting access error stack frame contains the
converted function code in the TM field for the faulted access. To
maintain cache coherency, MOVES accesses to write the
OinstructionO address space must be preceded by invalidation
of the instruction cache line containing the referenced location.
