The SPI read command is performed with 16 clock pulses. Multiple byte read command is
performed adding blocks of 8 clock pulses at the previous one.
bit 0: READ bit. The value is 1.
bit 1: MS bit. When 0, does not increment the address; when 1, increments the address in
multiple reads.
bit 2-7: address AD(5:0). This is the address field of the indexed register.
bit 8-15: data DO(7:0) (Read mode). This is the data that is read from the device (MSB first).
bit 16-...: data DO(...-8). Further data in a multiple byte read.

SPI write
Figure 9. SPI write protocol
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.
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.
