why 7441a can not read the HDCP key?

     As the datasheet of 7441a mentioned,  7441a has a HDCP eeprom and after reset 7441a would read HDCP key automatically,but in my system the HDMI MAP register 0x04[5:4] indicate HDCP  was not  read. Why ? My 7441a does not have HDCP key?

     When the input hdmi content is encrypted through 7441a which has not hdcp key, what will happen?
