Interrupt Status/Interrupt Acknowledge Register
Access
Address
Reset Value
Depending on the corresponding bits in register GMASK, an interrupt indication in this
register will be flagged at pin INTA. If an interrupt bit is masked (set to ’1’) in register
GMASK, system software has to poll this register in order to get status information of the
disabled interrupt bit.

Interrupt Overflow
This bit indicates that interrupt information has been lost due to overload
conditions of the internal interrupt controller. This interrupt indicates a
severe system problem. If this bit is set and INTOF is not masked in
register GMASK, the interrupt pin INTA will be asserted. INTOF is
cleared, when an ’1’ is written to this bit.

Local Bus Interrupt
The MUNICH256 supports bridging of interrupts from the local bus to the
PCI bus. In this application the pin LINT is used as an input and as soon
