5.3.1
SPI read
Figure 7. SPI read protocol
The SPI Read command is performed with 16 clock pulses. The 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 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 readings.

SPI write
Figure 9. SPI write protocol
The SPI Write command is performed with 16 clock pulses. The multiple byte write
command is performed adding blocks of 8 clock pulses at the previous one.
