MCU.
(1) Power-down operation of M34514T-MCU
Although the actual chip of each MCU is placed in the power-down mode by executing a
combination of EPOF and POF instructions, the M34514T-MCU is placed in the power-down
mode by only the POF instruction.
In the M34514T-MCU, the EPOF instruction does not have any effect.
