Command Structure

The three most significant bits of the command (Bit 5 to Bit 7) indicates the command

type. Bit 0 to Bit 4 describes the target address when reading or writing a control or sta-

tus register. In all other commands Bit 0 to Bit 4 have no effect and should be set to 0 for

compatibility reasons with future products.
