For the MC68030, PLOAD searches the address translation cache for the specified
effective address. It also searches the translation table for the descriptor corresponding
to the specified effective address. It creates a new entry as if the MC68030 had
attempted to access that address. Sets the used and modified bits appropriately as part
of the search. The instruction executes despite the value of the E-bit in the translation
control register or the state of the MMUDIS signal.
The < function code > operand is specified in one of the following ways:
The effective address field specifies the logical address whose translation is to be
loaded.
PLOADR causes U bits in the translation tables to be updated as if a read access had
occurred. PLOADW causes U and M bits in the translation tables to be updated as if a
write access had occurred.
