ADV7842 Pin C11 Test8 connection issue

   Here, one of our key visit customer Hikvision HZ is using ADV7842 who found one description conflict on ADV7842 datasheet and hardware manual (UG-214) for Pin C11 Test8 connection;

   on the datasheet, the C11 is recommended to connect to ground by one 4.7K ohm resistor;  but on the UG214, C11 is recommended to tie to 3.3V by 4.7K resistor;

   and on the EVAL schematics, there is reserved both circuit, but default is to install the 4.7K resistor that connect to ground;

   you can see attached printed page;


   please help to double check which connection is right to the normal operation of ADV7842? or both can be used? Thanks.
