(10) UF0 interface 0 register (UF0IF0)
This register stores the value that is to be returned in response to the GET_INTERFACE wIndex = 0 request.
This register is read-only, in 8-bit units.
When the SET_INTERFACE request is received, its wValue is automatically written to this register.
If the SET_INTERFACE request is processed by FW, wIndex and wValue are decoded, and the setting of endpoint
is automatically changed. At this time, the status bit of the target endpoint and DPID are automatically cleared to
0, depending on the setting. The FIFO is not cleared automatically.
Caution Do not execute a write access to this register. If written, the operation is not guaranteed.
