This interrupt is triggered every time an HDMI RX cable connection or disconnection (HPD level transition) occurs. The callback function must perform the following:
- Enable or disable the differential input clock buffer depending on whether cable
connection or disconnection occurs, respectively.
void XHdmiphy1_IBufDsEnable (XVphy *InstancePtr, u8 QuadId, XVphy_DirectionType Dir, u8 Enable);
- Clear HDMI PHY RX TMDS Clock ratio when
cable is disconnected:
XV_Rx_Hdmiphy1Ptr->HdmiRxTmdsClockRatio = 0;
- Reset and clear the connection related information in the HDMI 2.1 RX Interrupt handling layer data structure when cable is disconnected. Conversely, when the cable is connected, update and set the connection related information.
