Are there internal 5k1 resistors on the CC1/2 lines of the MP2724 chip?

Hi there,

I am currently working with the eval board of the MP2724. It works pretty nice and im pretty confident about it, but there is one thing I am wondering about. On the board I cannot find the 5k1 resistors on the CC1 and CC2 lines. So I would like to ask if they are internal. There is also the CC_CFG register to enable sink mode. I think it could be the internal FET to activate the resistors, but I am not quite sure.
I ask the question because there is no power coming from the USB-C cables. I have tested three different ones. But when I connect a normal power supply, everything works just fine.

Update:

I just tested it myself. There are no internal 5k1 Ohm resistors. I just soldered two 5k1 resistors to the clips of CC1 and CC2 and the GND. After that the USB-C worked fine.
