4.24 Interrupt Pin Register
The value read from the interrupt pin register is function dependent and depends on the interrupt signaling mode,
selected through bits 2
1 (INTMODE field) of the device control register (PCI offset 92h, see Section 4.33) and the
state of bit 29 (INTRTIE) in the system control register (PCI offset 80h, see Section 4.29). When the INTRTIE bit is
set, this register reads 01h (INTA) for both functions. See Table 4
6 for a complete description of the register contents.
