Partial I/O Data
- All voltage rails were measured to be near 0V

.. note::

The power consumption on the vdda_1v8 rail is not indicitive of the SoC's power consumption due to an oscillator on the rail
that has significant current consumption.

.. note::

The measurements shown are from an AM62Px SK rev E1-1. Results may vary based off of the board revision being used.

Further optimizations are possible for these low power modes. Please refer to the AM62x Power Consumption App Note (https://www.ti.com/lit/pdf/spradg1)
