Doc ID 022018 Rev 1
The SPI Write command is performed with 16 clock pulses. The multiple byte write
command is performed adding blocks of 8 clock pulses to the previous one.
bit 0: WRITE bit. The value is 0.
bit 1: MS bit. When 0, this bit does not increment the address, when 1, it increments the
address in multiple writes.
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 writes.

Multiple bytes SPI write protocol (2 bytes example)

SPI read in 3-wire mode
The 3-wire mode is entered by setting to ‘1’ bit SIM (SPI serial interface mode selection) in
CTRL_REG4.
Figure 11.
SPI read protocol in 3-wire 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, this bit does not increment the address, when 1, it increments the
address in multiple reads.
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).
The multiple read command is also available in 3-wire mode.
