There is only one allowed sample clock configuration in AUX Power-Down operational mode with AUX_SYSIF:OPMODEREQ.REQ equal to LPPD.
In the scenario, the user must enable the sample clock generation when AUX_SYSIF:OPMODEREQ.REQ = LP and then request LPPD.
Generation of the sample clock is not allowed when AUX_SYSIF:OPMODEREQ.REQ = PDA.
