The SPI write command is performed with 16 clock pulses. The multiple byte write
command is performed by adding blocks of 8 clock pulses to the previous one.bit0: WRITE
bit. The value is 0.bit1-7: address AD(6:0). This is the address field of the indexed register.
bit8-15: data DI(7:0) (write mode). This is the data that is written in the device (MSb first).
bit16-...: data DI(...-8). Further data in multiple byte writes.
