4.7.2
Mailbox interrupts are stored in an internal interrupt FIFO which is located inside the
MUNICH256 and can be read from either the local microprocessor or (for test purposes)
via the chip internal bridge from the host processor located on the PCI bus.
The interrupt FIFO triggers the LINT pin which indicates that there is at least one interrupt
vector available. Then the interrupt FIFO can be read from either PCI side or local bus
side. The interrupt vector contains a last indication when there is no further interrupt
vector stored in the internal interrupt FIFO.
