Note1) Data is not concerned with the signal of CSb but is read into the internal shift register by the rising edge of CLK.

Note2) The contents of a shift register are read into the internal instruction decoder by the rising edge of CSb.

note3) An instruction and data should surely input 8 bits. In case of entering over than 8 bits data, valid data is last 8 bits
