SPI write
Figure 19. 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 1-7: address AD(6:0). 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 in the device (MSb first).
bit 16-...: data DI(...-8). Further data in multiple byte writes.
