Bit Field
ConfigBuf’s
Since the UDC is forwarding the GetDescriptor Command to the Application, the UDC
does not maintain Configuration Buffer space within the UDC core.
StringBuf’s
Since the UDC is forwarding the GetDescriptor Command to the Application, the UDC
does not maintain String Buffer space within the UDC core.

USB register set provides Special Function Registers (SFR’s) for eight receiving
Endpoints and eight transmitting Endpoints. In addition, Interrupt and Status SFRs will
be provided for fast data processing. Each individual endpoint’s Transmit and Receive
FIFO can be accessed via XBUS. Transmit and Receive FIFO interrupts will be
generated for each endpoint.
Note: Please note, that the SETUPxx and RXRR registers are one time read-only
