can't enable ADV7511 CEC interrupt

I'm trying to implement CEC function by myself, based on "ADV7511_Programming_Guide" Rev G.


Here is my setting for CEC:

1. enable CEC power & clock/timing

2. enable CEC Tx & Rx interrupt

3. Physical & Logical addressing

4. ARC protocol


Now I got stuck in step 2.

  * 0x95[0~5] = 1; enable interrupt

I read the value back to check if it is changed, after I've written it. But it is the same as before.


I've check the datasheet, but found no clue.


Any help would be much appreciated.
