as 0, 1, 2, or 3. These mode numbers are an encoding of
two control bits: Clock Phase and Clock Polarity.
Clock Phase indicates the relationship of the clock to the
data. When the clock phase is '0', it means that the data is
registered as an input on the leading edge of the clock and
the next data is output on the trailing edge of the clock.
When the clock phase is '1', it means that the next data is
output on the leading edge of the clock and that data is reg-
istered as an input on the trailing edge of the clock.
Clock Polarity controls clock inversion. When clock polarity
is set to '1’, the clock idle state is high.
