Offset:
Register Name:
Access Type:
Reset Value:
• ALLOC: Endpoint Memory Allocate
Set to allocate the endpoint memory.
Clear to free the endpoint memory.
Cleared by hardware upon receiving a USB reset (except for the endpoint 0).
Note that after setting this bit, the user should check the CFGOK bit to know whether the allocation of this endpoint is
correct.
• EPBK: Endpoint Banks
Set to select the number of banks for the endpoint:
For control endpoints, a single-bank endpoint (00b) should be selected.
Cleared by hardware upon receiving a USB reset (except for the endpoint 0).
