PLOAD
Instruction Fields:
MOTOROLA
Effective Address field—Specifies the logical address whose translation is to be loaded
R/W field—Specifies whether the tables should be updated for a read or a write.
1—Read
0—Write
into the address translation cache. Only control alterable addressing modes are
allowed as listed in the following table:
The effective address field must provide the MC68851 with the
effective address of the entry to be loaded into the address
translation cache, not the effective address describing where the
PLOAD operand is located. For example, to load an address
translation cache entry to map a logical address that is
temporarily stored on the system stack, the instruction PLOAD
[(SP)] must be used since PLOAD (SP) would load an address
translation cache entry mapping the system stack (i.e., the
effective address passed to the MC68851 is the effective
address of the system stack, not the effective address formed by
the operand located on the top of the stack).
