Effective Address field—Specifies the logical address to be evaluated and compared
Register field—Specifies the main processor address register to be used in the
14
against specified main processor address register. Only control alterable addressing
modes can be used as listed in the following table:

The effective address field must provide the MC68851 with the
effective address of the logical address to be validated, not the
effective address describing where the PVALID operand is
located. For example, to validate a logical address that is
temporarily stored on the system stack, the instruction PVALID
VAL,[(SP)] must be used since PVALID VAL,(SP) would validate
the mapping on 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).
