SPI read in 3-wire mode

3-wire mode is entered by setting bit SIM (SPI serial interface mode selection) to ‘1’ in

CTRL_REG4 (23h).

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, does not increment the address, when 1, 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 is read from the device (MSb first).

The multiple read command is also available in 3-wire mode.
