VDP_STATUS_WSS_CGMS bit from ADV7850

Hi

 

My test shows that both VDP_STATUS_GS_VPS_PDC_UTC_CGMSTB and VDP_STATUS_WSS_CGMS are 1s simultaneously. According Register Map Rev A, VDP_STATUS_WSS_CGMS indicates the detection of CGMS Type A and VDP_STATUS_GS_VPS_PDC_UTC_CGMSTB indicates the detection of CGMS Type B. But it should not possible that both are detected at the same time. Where I am wrong?

 

Thanks,

Robert
