Power-On Sequence
• Power-off order
1. In the reverse order of powering-on, first turn off the 1.7 V/1.8 V/1.9 V/2.0 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 1.7 V/1.8 V/1.9 V/2.0 V power is off. The system
design must ensure that these undefined states do not cause erroneous system operation.
