The SPI write command is performed with 16 clock pulses. A multiple byte write command
is performed by adding blocks of 8 clock pulses to the previous one.
bit 0: WRITE bit. The value is 0.
bit 1: MS bit. When 0, does not increment the address. When 1, increments the address in
multiple writes.
bit 2 -7: address AD(5:0). This is the address field of the indexed register.
bit 8-15: data DI(7:0) (write mode). This is the data that is written inside the device (MSB
first).
bit 16-...: data DI(...-8). Further data in multiple byte writes.
