Questions about ADXRS450---We don't know exactly how long the output delay is

Hello guys!

 

We have noticed that in the end of the ADXRS450 primary signal chain, there is a data latching register. However,  the update of this register, according to the datasheet, is about 500Hz. So...if this means, the highest rate of gyroscope's output is 500Hz? Or in other words, if this means the data we get from LPF can only be changed every 2ms?

 

 

In fact, our primary goal is to  confirm the output delay as precisely as we can. We have known the group delay of LPF, the SPI transmit delay, etc, but we just can't make sure the delay caused by register.

 

So what can we do? Please help us....THANK YOU~
