Problem with WSS output from ADV7180

I am trying to readback the decoded WSS data (for PAL) from the BT stream and I observed that

the CGMS_WSS[7:0] inVDP_CGMS_DATA_2 byte is correct. However. the data stored in

CGMS_WSS[13:8] in VDP_CGMS_WSS_DATA sometimes gives the correct data but not all the time.


BTW, I am generating constant WSS data and providing it as input to the Decoder. When  I try for CGMS,

I am always getting the correct data back.


Could you please suggest what may be going wrong.
