NXP Semiconductors QorIQ LX2160A - 2.1.4 Current and power measurement; 2.2 Clocks

The LX2160ARDB follows the power supply sequencing requirements as detailed in
QorIQ LX2160A Data Sheet.
2.1.4 Current and power measurement
The LX2160ARDB implements onboard current and power measurements only for the
VDD supply. For selected other supplies, monitoring resistors are available. The table
below lists all measurable supplies.

GVDD External meter 0.0005
Power supplies not listed in the above table are considered as low-current/incidental
supplies and are not instrumented for power measurement.
2.2 Clocks
The LX2160ARDB provides all the clocks required for the processor and peripheral
interfaces. The figure below shows the LX2160ARDB clock architecture.
