Note: In a non-segmented memory mode, the whole DPP register is still used for the
calculation of the physical 24-bit address.
A DPP register can be updated via any instruction that is capable of modifying an SFR.
Note: Due to the internal instruction pipeline, a new DPP value is not usable for the
operand address calculation of the instruction immediately following the
instruction updating the DPPx register.
