Question

When the LIS3DH FIFO is enabled, reading 6-byte data registers again and again will make the FIFO pop data automatically. How about only reading three high bytes OUT_X_H, OUT_Y_H and OUT_Z_H?

Hello Naue,

Yes, it works the same way as reading 6-byte data registers when only reading three high bytes it does not no matter if LIS3DH is in normal mode and low power mode.

For more information, please check the attached detail sheet and visit www.st.com/mems

Thank you,
