Waveforms and recommended times at power on/off are shown in figure 25.1.
Recommended Power On/Off Times
The recommended times shown above do not require strict settings.
The state undefined term indicates that pins are at the power rising stage. The pin state is stabilized
at VccQ (min) attain time. However, a power-on reset (
after VccQ (min) attain time and clock oscillation settling time. Set the state undefined term less
than 10 ms.

Power-off order
1. In the reverse order of powering-on, first turn off the 1.5 V power, then turn off the 3.3 V
2. Pin states are undefined while only the 1.5 V power is off. The system design must ensure
3. When the power is turned off, make sure that the voltage of the 1.5 V power is lower than
power within 1 ms. It is recommended that this interval will be as short as possible.
