Detailed information

YASKAWA JAMSC-C8120 Matrix switch card

For a multifunction device, all functions may use the same INTx# line or each may have its own (up to a maximum of four functions) or any combination thereof. A single function can not generate an interrupt request on more than one INTx# line. The slave PCI accepts the VMEbus interrupts through lines that are defined by the BIOS. The JAMSC-C8120 defines which interrupt line to utilize depending on which system requires the use of the line. The PCI-to-VME Bridge has the capability of generating a Non-Maskable Interrupt (NMI) via the PCI SERR# line. Table 3-5 describes the register bits that are used by the NMI. The SERR interrupt is routed through certain logic back to the NMI input line on the CPU. 

The CPU reads the NMI Status Control register to determine the NMI source (bits set to 1). After the NMI interrupt routine processes the interrupt, software clears the NMI status bits by setting the corresponding enable/disable bit to 1. The NMI Enable and Real-Time Clock register can mask the NMI signal and disable/enable all NMI sources.
