The device that recognizes the address responds by pulling SDIN low during the ninth clock cycle, acknowledging
the data transfer. The control follows in the next two eight-bit blocks. The stop condition after the data transfer is a
rising edge on SDIN when SCLK is high (see Figure 3-2).
The 16-bit control word is divided into two parts. The first part is the address block, the second part is the data block:
B[15:9]
B[8:0]
