This field shall be written to select the size of each endpoint bank. The maximum size of each endpoint is specified in
1 on page 362
This field is cleared upon receiving a USB reset (except for the endpoint 0).
This field shall be written to select the number of banks for the endpoint:
For control endpoints, a single-bank endpoint (0b00) shall be selected.
This field is cleared upon receiving a USB reset (except for the endpoint 0).
Writing a one to this bit will allocate the endpoint memory. The user should check the CFGOK bit to know whether the allocation
of this endpoint is correct.
Writing a zero to this bit will free the endpoint memory.
This bit is cleared upon receiving a USB reset (except for the endpoint 0).
