AFE4404: How to determine values to use for PROG_TG_STC and PROG_TG_ENDC?

Part Number: AFE4404

I need to adjust the ADC_RDY period to be 62.5 us instead of the current value of .25 us. This is because I need the Sensor Controller found on the TI C2650 to sample the AFE. How do I set the  PROG_TG_STC and PROG_TG_ENDC registers? I know they allow you to have a custom ADC_RDY signal but I don't understand how to calculate the numbers. The datasheet does not say either. I tried using the AFE4404EVM software but I don't see an option for calculating those registers. Would really appreciate it if someone can point me in the right direction. Thanks.
