SPI write
Figure 9.
The SPI Write command is performed with 16 clock pulses. Multiple byte write command is
performed adding blocks of 8 clock pulses at 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 writing.
Figure 10. Multiple bytes SPI write protocol (2-byte example)
SPI read in 3-wire mode
3-wire mode is entered by setting to ‘1’ bit SIM (SPI serial interface mode selection) by
internal register.
