XV_HDMITXSS_HANDLER_STREAM_DOWN - 3.2 English

This interrupt is triggered every time the Video PHY Controller /HDMI GT Subsystem is reconfigured and the output clock is not stable for the HDMI 1.4/2.0 TX Subsystem to stream video.

The callback function might disable the TX TMDS clock by calling the Video PHY Controller /HDMI GT Subsystem API:

void XVphy_Clkout1OBufTdsEnable(XVphy *InstancePtr, 
                                XVphy_DirectionType Dir,
                                u8 Enable);
