hello everyone
during the communication of the USB,i pull up the USB line, the routine enter into the interrupt of usb err.
but,i read the register of USB0_ERRSTAT,it's value is 0x00,
how can i know the reason of the err?
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
