SPI Write
Figure 7.
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 : 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 will be written inside the device (MSb
first).
bit 16-... : data DI(...-8). Further data in multiple byte writing.
Figure 8.
SPI Read in 3-wires mode
3-wires mode is entered by setting to 1 bit SIM (SPI Serial Interface Mode selection) in
CTRL_REG2.
