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.
