IWR6843AOP: Frame Rate Ignoring frameCfg Setting

Tool/software:

Hello, 

I'm working with the IWR6843 3D People Tracking demo and experiencing unexpected frame rate behavior that doesn't match my configuration.

Configuration:

frameCfg 0 2 96 0 900.00 1 0
trackingCfg 1 2 800 1 46 96 900

Both commands are set to 900ms frame period, but the actual output behavior is around 55ms! Can it be overwritten somewhere else in the code? 

Cheers,

/S
