USB setup command index and value registers (USCI and USCV)
When a Setup/Data packet is received over the USB, the 8 bytes of data received are
stored in a command buffer. The USB setup command index register (see
determines which one of the eight bytes in the buffer is read using the USB setup
command value register (see
