The waveforms in Figure 4-1 and Figure 4-2 show the power up and down sequence of the different power rails measured on the AM62x discrete power EVM.

Figure 4-1 Measured Power-On Sequence for AM62x

On the AM62X discrete power EVM, the power-down sequence is triggered by the ramp down of the 3.3 V, VDDSHVx rail as shown in Figure 4-2.
