SYNTAX      DIRECT   [<LABEL>] LPH <dma>
            INDIRECT [<LABEL>] LPH {ind}[,<next ARP>]

OPERANDS    0 . dma . 127; 0 . next ARP . 7.

EXECUTION   (PC) + 1 . PC
            (dma) . P register (31-16)

DESCRIPTION The P register high-order bits are loaded with the contents
            of data memory. The low-order P register bits are unaffected.

            The LPH instruction is primarily useful for restoring the
            high-order bits of the P register after subroutine calls or
            interrupts.
