The IP issues an IRQ to the Nios II processor if the DPTX_TX_CONTROL registers HPD_IRQ_EN is 1 and the IP detects a new HPD event. HPD_EVENT provides information about the event that caused the interrupt. The interrupt and HPD_EVENT bit fields are both cleared by writing to the DPTX_TX_STATUS register.
