8 CONTROL AND STATUS REGISTERS
The internal W9968CF control registers can be accessed by performing one of the two vendor-specific
requests on the default pipe (Endpoint 0): Get W9968CF Control for read access and Set W9968CF
Control for write access. All W9968CF control registers are 16-bit wide and can be accessed in WORD
only. Table 8.1 shows the control register map.
