3. Connect the 24-V DC power adapter provided with the kit to the CY4531 EZ-PD CCG3 EVK base board power jack J1.
Observe LED1 on the CCG3 daughter card and CCG base board glow green to indicate power is ON, and LED2 on
CCG base board blinks orange to indicate the CCG firmware is executing.
4. Connect the USB Type-C to Type-A adapter board provided with the CY4531 EZ-PD CCG3 EVK to the Type-C port
(J3) of the CCG base board.
5. Plug in a USB drive (not provided with the kit) into the Type-C to Type-A adapter board. Verify your setup as shown in
. To evaluate SuperSpeed USB data transfers, it is recommended to use a SuperSpeed USB flash drive.

6. Observe the enumeration of the USB drive connected to the Type-C to Type-A adapter board on the host PC
connected via the CY4531 EZ-PD CCG3 EVK
’s base board and daughter card. Verify functionality by accessing files
on the connected USB drive from the PC.
7. Disconnect the Type-C to Type-A adapter board and connect it upside down to reconnect the SuperSpeed USB drive.
8. Observe the enumeration of the USB drive connected to the Type-C to Type-A adapter board on the PC connected via
the CY4531 EZ-PD CCG3 EVK base board and daughter card even with the Type-C to Type-A adapter board flipped.
Also observe the SuperSpeed USB data transfer speed by transferring files. This demonstrates orientation adjustment
of the USB Type-C interface.
5.1.3 Explanation of Functionality
By flipping over the USB Type-C to Type-A adapter board and reconnecting to the setup, we reversed the order of the four
channels from the original setup. This demonstrates functionality in a use case scenario where a Type-C cable is connected
between the host and client with the ends reversed. The reverse order will not affect the enumeration process due to the
reversible characteristics of Type-C cables.
