This field contains the endpoint token.
This field contains the size of each pipe bank.
This field is cleared upon sending a USB reset.
This field contains the number of banks for the pipe.
For control endpoints, a single-bank pipe (0b00) should be selected.
This field is cleared upon sending a USB reset.
Writing a one to this bit will allocate the pipe memory.
Writing a zero to this bit will free the pipe memory.
This bit is cleared when a USB Reset is requested.
