6.4.5 Status and interrupts on PCI-bus
= page table
= allocated memory space
The SAA7134HL provides a set of status information about internal signal processing,
video and audio standard detection, peripheral inputs and outputs (pins GPIO) and
behavior on the PCI-bus. This status information can be conditionally enabled to raise an
interrupt on the PCI-bus, e.g. completion of a certain DMA channel or buffer, or change in
a detected TV standard, or the state of peripheral devices.
The cause of an issued interrupt is reported in a dedicated register, even if the original
condition has changed before the system was able to investigate the interrupt.
