With ADRF6510 offset correction loop disabled, is a Cofs voltage proportional to the output baseband DC offset or is it voltage reset?

If we put the OFDS line to disable offset correction loop (a switch on Figure
46 is off) is a voltage on capacitor Cofs proportional to the output baseband
DC offset or is this voltage reset?

 

The voltage on the cap will slowly degrade to an off state. It should be close
to ground.  There may be some small residual voltage where the FETs are off and
don’t degrade the voltage anymore.  I’m guessing it should be 0.5V or less.
