IRQ Status 1 Register
| SCANLINE0_IRQ | Line IRQ status. The Line interrupt is generated when a programmed line number is reached. |
| FIFO_UNDERRUN_IRQ | FIFO underrun warning IRQ status. The FIFO underrun warning interrupt is generated if one of the layer FIFOs is empty and pixel data is read from the FIFO. This can occur if the color frame buffer length is not defined properly or the master bus performance is too low, such that the pixel data cannot be read in time. |
| BUS_ERROR0_IRQ | Bus error IRQ status. The Bus error interrupt is generated if an error occurs on the AXI bus. |
| REG_RELOAD_IRQ | Register reload IRQ status. The Register reload interrupt is generated, if a vertical blanking reload was programmed and the first line after the active area is reached. |
