4.24 Interrupt Pin Register

The value read from this register is function dependent. The default value for function 0 is 01h (INTA), the default value for function 1 is 02h (INTB), the default value for function 2 is 03h (INTC), the default value for function 3 is 01h (INTA), the default value for function 4 is 01h (INTA), the default value for function 5 is 01h (INTA). The value also depends on the values of bits 28, the tie-all bit (TIEALL), and 29, the interrupt tie bit (INTRTIE), in the system control register (PCI offset 80h, see Section 4.29). The INTRTIE bit is compatible with previous TI CardBus controllers, and when set to 1, ties INTB to INTA internally. The TIEALL bit ties INTA, INTB, INTC, and INTD together internally. The internal interrupt connections set by INTRTIE and TIEALL are communicated to host software through this standard register interface. This read-only register is described for all PCI7x21/PCI7x11 functions in Table 4−6.
