2.2.1 Recommended power-up sequence

For the power-up sequence please refer to the following figure, where:

 Trise is the time for the power supply to rise from 10% to 90% of its final value

 Twait is the delay between the end of the Vdd_IO ramp (90% of its final value) and the

start of the Vdd ramp
