IIS3DWB FIFO readout wrap-around

Hi
does the wrap-around feature work for the FIFO output registers as well?
Can I just enable wrap-around in CTRL5 register, and read 7*number of words in FIFO bytes starting with register 78h to get the entire content of the FIFO?

I have a hard time retrieving the data in time, Tiva C lib takes way too long to start and stop SPI transactions. Now I don't have the hw with me to simply test it.

thanks,
Lorand

    Hi @LKert ,

    As described in the Application Note, the wrap around is automatically done when you are using the FIFO: you will read the 9 output registers:
