It is considered that this request does not come to Interface
because there is no function selector value, though it is reserved
for bmRequestType.
When this request is received, the hardware makes an automatic
STALL response.
It is considered that this request does not come to Interface

When this request is received, the hardware makes an automatic
STALL response.
Returns the string descriptor.
When this request is received by the SETUP token, the hardware
generates the CPUDEC interrupt request for FW. FW decodes
the contents of the request from the CPUDEC interrupt request,
and writes the data to be returned to the host, to the UF0E0W
register.
Rewrites the device descriptor.
When this request is received by the SETUP token, the hardware
generates the CPUDEC interrupt request for FW. FW decodes
the contents of the request from the CPUDEC interrupt request,
and the writes the data for the next control transfer (OUT) to the
UF0DDn register (n = 0 to 17).
Rewrites the configuration descriptor.
When this request is received by the SETUP token, the hardware
generates the CPUDEC interrupt request for FW. FW decodes
the contents of the request from the CPUDEC interrupt request,
and the writes the data for the next control transfer (OUT) to the
UF0CIEn register (n = 0 to 255).
Rewrites the string descriptor.
When this request is received by the SETUP token, the hardware
generates the CPUDEC interrupt request for FW. FW decodes
the contents of the request from the CPUDEC interrupt request,
and loads the data for the next control transfer (OUT).
When this request is received by the SETUP token, the hardware
generates the CPUDEC interrupt request for FW. FW decodes
the contents of the request from the CPUDEC interrupt request,
and performs the necessary processing.
