ADV7610 - completely disable freerun mode

Hello,

We are trying to completely disable the ADV7610 freerunning mode, as we do not want to receive any pixel valid when the HDMI cable is unplugged.
However, we still see valid black RGB pixels (all zeros) coming out of the ADV7610 when cable is unplugged.

Here is a part of our configuration:

0x44 (CP), 0xBA = 0x00
-> HDMI_FRUN_EN = 0
-> HDMI_FRUN_MODE = 0

0x44 (CP), 0xBF = 0x10
-> CP_FORCE_FREERUN = 0
-> CP_DEF_COL_AUTO = 0
-> CP_DEF_COL_MAN_VAL = 0

0x44 (CP), 0xC9 = 0x2C
-> DIS_AUTO_PARAM_BUFF = 0

Is it possible to completely disable the freerun mode to avoid having any valid pixel sent from the ADV7610 when HDMI cable is unplug?

Thanks for you help,
Jon
