I would like to implement a software interrupt for the IMU data -- DELT_ANG and DELT_VEL.
I believe these data represent accumulated data per the decimation filter (figure 20)
I have set the DEC_RATE to 24 to reduce the output sample rate to 98.4 SPS (2460 ÷ 25).
I have NOT changed FNCTIO_CTRL from its default value (0x000D).
This suggests that the DIO2 line is set as dataready.
Figure 4 shows the dataready signal goes from low to high when we have data valid.
Does the DIO2 line go low-to-high for each word that is read?
Or does the dataReady go low-to-high when we have a new set of data based on the DEC_RATE?
Is there some DIOx signal I can access that provides a transition when a new DEC_RATE dataset is available?
when the dataReady line goes low, how long does it stay low?
