3.5. Power-Down Sequence
When the VCC is shut down, voltage should drop quickly with a drop time of less than 50 ms. It is
recommended to use a voltage regulator that supports fast discharge.
To avoid abnormal voltage condition, if VCC falls below specified minimum value, the system must initiate
a power-on reset by lowering VCC to less than 100 mV for at least 100 ms.
