This bit is cleared upon receiving a USB reset.
1: The automatic bank switching is enabled.
0: The automatic bank switching is disabled.
This bit is cleared upon receiving a USB reset.
1: The endpoint direction is IN (nor for control endpoints).
0: The endpoint direction is OUT.
This field shall be written to select the size of each endpoint bank:
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
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).
