The SPI read command is performed with 16 clock pulses. A multiple byte read command is
performed by adding blocks of 8 clock pulses to the previous one.
bit 0: READ bit. The value is 1.
bit 1: MS bit. When 0, do not increment address; when 1, increment address in multiple
reading.
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 multiple byte reading.

SPI write protocol
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, do not increment address; when 1, increment address in multiple
writing.
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 to the device (MSb first).
bit 16-... : data DI(...-8). Further data in multiple byte writing.
