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

.. note::

The power consumption on the vdda_1v8 rail does not include an
oscillator on the rail that has significant current consumption.
Since previous SDK power measurements include the oscillator on the
rail, the reported power measurements are significantly different from
the current reported power measurements.

.. 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)
