<p>DisplayPort interrupts occur on the HPD signal line when the DisplayPort cable is connected/disconnected or when the RX device sends a pulse. The user hardware design must contain an interrupt controller which the DisplayPort TX instance's interrupt signal is connected to. The user application must enable interrupts in the system and set up the interrupt controller such that the XDp_TxHpdInterruptHandler handler will service DisplayPort interrupts. When the XDp_TxHpdInterruptHandler function i
