MOTOROLA

0
Effective Address field—Specifies a control alterable address. The address translation
14
cache entry for this address is invalidated. Valid addressing modes are in the
following table:
1
0
13
The address field must provide the memory management unit
with the effective address to be flushed from the address
translation cache, not the effective address describing where the
PFLUSH operand is located. For example, to flush the address
translation cache entry corresponding to a logical address that
is temporarily stored on top of the system stack, the instruction
PFLUSH [(SP)] must be used since PFLUSH (SP) would
invalidate the address translation cache entry mapping the
system stack (i.e., the effective address passed to the memory
management unit is the effective address of the system stack,
not the effective address formed by the operand located on the
top of the stack).
