SPI write

Figure 17. 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 -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 inside the device (MSb

first).

bit 16-... : data DI(...-8). Further data in multiple byte writes.
