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 10. Multiple bytes SPI Write protocol (2 bytes example)
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.
Figure 11. SPI Read protocol in 3-wires mode
The SPI Read command is performed with 16 clock pulses:
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 will be read from the device (MSb
first).
Multiple read command is also available in 3-wires mode.
