the host PC should look similar to that in
Figure 16 .

9. A successful PD contract can be seen from the PD message sequence. From Figure 16 , it is clear that the
Type-C device used in this example is a UFP (Sink/Power Consumer) and the Type-C port of the CY4532
CCG3PA EVK is a DFP (Source/Power Provider). Looking at the
‗VBUS‘ column in
Figure 16 , it can be seen that
the VBUS voltage is still set to 5 V at the end of the power contract negotiation.
