What does circular burst-mode (rounding) read from the output registers mean?

Hi,

I am implementing the IIS3DWB vibrometer. There is a register that allows circular burst-mode (rounding) read from output registers. What does it mean?

Thanks.

Hi @DLim.16​ , burst-mode read is a one-shot / single data output read. The circular burst-mode (rounding) read function is used for automatically rounding from address FIFO_DATA_OUT_Z_H to FIFO_DATA_OUT_TAG in the device in order to allow user to read many data with a unique multiple read. The ROUNDING<1:0> bits are used to auto address the correct registers for a circular burst-mode read of the device following one of the following patterns:

00 = no rounding

01 = XL only (no Temp)

Btw, IIS3DWB is in evaluation status... where did you get the datasheet? Regards
