15 (LDO1) is the first rail to be enabled in a sequence, followed by strobe

1 through strobe 7. For more information, see the Wake-Up and Power-Up Sequencing section.

5 Device Comparison Table(1) The device comparison table summarizes the default regulator output voltages and sequencing order settings for the four available variants of the TPS65217 device. For details on the preprogrammed register map values that determine these voltage and strobe sequence settings, refer to Register Maps. For details on specific applications, refer to the Powering the AM335x with the TPS65217x user'
