ADIS 16488 Sync

I am planning to drive a 2 kHz external clock and use DEC_RATE to make the output rate slower. I want to make the phase of this slower output deterministic for each start-up cycle. That is, I need to synchronize the IMU output with another event occurring at this slower rate.  The 2kHz clock is already synchronized to the other event. What I need to know is how to sequence the IMU so that I know when the last Average/Decimation stage (the one controlled by DEC_RATE) starts counting. Can I assUme that the count into that stage resets when the external clock option is enabled in the FNCTIO_CTRL register or the DEC_RATE is set?
