Address is upper 3bit in serial data, DATA is lower 8bit. (MSB first base)

SDATA is taken in to the inside with a positive edge SCLK, then SDATA is taken in to the register with a positive edge

of SSTB.

In the case that the clock number of SCLK is 12 or more, the data of 11CLK of before SSTB comes into effect.
