• Power-off order
1. In the reverse order of powering-on, first turn off the 1.9 V power, then turn off the 3.3 V
power within 1 ms. This interval should be as short as possible.
2. Pin states are undefined while only the 1.9 V power is off. The system design must ensure
that these undefined states do not cause erroneous system operation.
