Note 1. Index specifies the starting index of the control registers to be accessed. An index
counter, loaded with the Index value, will be incremented by one after every two bytes of data
transferred.
Note 2. Length specifies number of data bytes transferred during the second phase of the
control transfer. It should be an even number value. If this field is zero, there is no data
transfer phase.
Note 3. Data0 is a word-sized data to be programmed into the control register indexed by the
Index field, no matter the Length field is zero or not. The internal index counter will be
incremented by one once Data0 is transferred.

control registers IN transfer. Length field should be an even number value. The W9967CF returns
STALL for any unrecognized or unsupported Get W9967CF Control request.
The W9967CF supports a Get W9967CF Control request for W9967CF
Set W9967CF Control
control registers OUT transfer. Length field should be an even number value. If the Length field is
zero, only Data0 is transferred with no data transfer phase. The W9967CF returns STALL for any
unrecognized or unsupported Set W9967CF Control request.
The W9967CF supports a Set W9967CF Control request for W9967CF
7.4.3 Descriptors
The W9967CF supports the standard USB descriptors as described below. The W9967CF returns
STALL if a request is received for any unrecognized or unsupported standard descriptor.
7.4.3.1 Device Descriptors
The W9967CF returns a Device Descriptor with the values shown in Table 7.5.
