AVI IF checksum error issue with ADV7626

We run into a case, which ADV7626 always stored avi InfoFrames regardless checksum error and register 0x47[0] was set 0 in HDMI Rx map.  Currently, ADV7626 doesn't discard InfoFrames data received from upstream if their checksum is incorrect.  With work around solution, I have to always check avi length and checksum before using the avi Infoframe data.


So my question is : Is there any other register I can use to config ADV7626 to stores infoframe data only if their checksum is correct?  or I misunderstood something with infoframe checksum error case described in the manual?
