4.24 Interrupt Pin Register
The value read from this register is function dependent. The default value for function 0 is 01h (INTA) and the default
value for function 1 is 02h (INTB). The value also depends on the value of bit 29, the interrupt tie bit (INTRTIE) in the
system control register (PCI offset 80h, see Section 4.31). The INTRTIE bit is compatible with previous TI CardBus
controllers, and when set to 1, ties INTB to INTA internally. This results in both functions reporting interrupts through
the INTA pin (01h). See Table 4
5.
