Hello,

In order to understand the results from the those registers I recommend that you take a look at the Reference Manual and sections 46.4.9, 46.4.10 and 46.4.11. These sections explain the bits in those registers, normally a 0x00 is read after a reset.

In addition, if you are working with USB I would also recommend that you take a look at SDK examples that focus on USB for the K64, as a reference.

Let me know if you have questions with the above mentioned,

Thank you,

Sabina
