4.6.2

SOURCE POWER DELIVERY OBJECTS (PDOS)

The PDOs defined in the USB PD Specification Section 10.2.2 are configurable within the PSF configuration. These are

the PDOs returned in the PD Source_Capabilities message and correspond to the capabilities of the Source power sup-

ply. Augmented PDOs (APDOs) are also supported for enabling Programmable Power Supply (PPS) operation.

4.6.3

SINK POWER DELIVERY OBJECTS (PDOS)

The PDOs defined in the USB PD Specification Section 10.2.2 are configurable within the PSF configuration. These are

the PDOs returned in the PD Sink_Capabilities message and correspond to the requirements of the Sink with respect

to Source capabilities. Note that the PDOs defined in the USB Power Delivery Specification Section 10.2.2 are defined

for Sources, but correspond to the Source PDOs the Sink is able to operate with.
