0 (OUT): The endpoint direction is OUT.
1 (IN): The endpoint direction is IN (nor for control endpoints).
• EPSIZE: Endpoint Size
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).
• EPBK: Endpoint Banks
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).
• ALLOC: Endpoint Memory Allocate
Writing a one to this bit will allocate the endpoint memory. The user should check the UOTGHS_DEVEPTISRx.CFGOK bit
