MCU.

(1) Power-down operation of M34570T-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 M34570T-MCU is placed in the power-down

mode by only the POF instruction.

In the M34570T-MCU, the EPOF instruction does not have any effect.
