Hi,
I have a question about ADV7482 antialiasing filters setting.
1) If "aa_filt_man_ovr" and "aa_filt_en" are default, are the registers selected by "insel" enable?
2) Should we set "aa_filt_man_ovr" to 1(Enable override) if we use "aa_filt_en"?
Best Regards,

Hi,
1) If "aa_filt_man_ovr" and "aa_filt_en" are default, are the registers selected by "insel" enable?
The selection of INSEL[4:0] register determines which filters are powered up at any given time & by default "aa_filt_en" register will be disabled. Please refer below snap for your reference.
2) Should we set "aa_filt_man_ovr" to 1(Enable override) if we use "aa_filt_en"?
Yes, AA_FILT_MAN_OVR must be enabled to change settings defined by INSEL[4:0].
