For fall time of the CORE power1.375V Room temperature,
there is a difference in the fall time (current consumption) at low temperature. Waveform see attach supplementary materials.
There can be problematic in that cut fell 1.375 V power upon the return from the interruption to 3.1 V power
would stand up? (After all of the power is turned on,POR_B will be canceled.)
Must be within 200 ms stood down as the specifications of the product,
but low temperatures at 200 ms after the voltage value is 0.75 V.
