The power-down mode of the M34551T2-MCU operates differently from that of the actual MCUs.
(1) Power-down operation of the M34551T2-MCU
While with the actual MCUs the power-down mode works by the "EPOF" and "POF" instructions,
with the M34551T2-MCU the power-down mode works only by the "POF" instruction.
With the M34551T2-MCU, the "EPOF" instruction is invalid.
