S5320 – PCI Match Maker: PCI Configuration Registers

Data Sheet

Interrupt Line Register (INTLN)

This register indicates the interrupt routing for the

S5320 controller. The ultimate value for this register is

system-architecture specific. For x86 based PCs, the

values in this register correspond with the established

interrupt numbers associated with the dual 8259 con-

trollers used in those machines. In x86-based PC

systems, the values of 0 to 15 correspond with the IRQ

numbers 0 through 15, and the values from 16 to 254

are reserved. The value of 255 (the controller’s default

power-up value) signifies either “unknown” or “no con-

nection” for the system interrupt. This register is boot-

loaded from the external boot memory or may be writ-

ten by the PCI interface.
