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_REG4.
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 is read from the device (MSb first).
Multiple read command is also available in 3-wires mode.
