4.22 CardBus I/O Limit Registers 0, 1
These registers indicate the upper address of a PCI I/O address range. They are used by the PCI1620 to determine
when to forward an I/O transaction to the CardBus bus, and likewise, when to forward a CardBus cycle to PCI. The
lower 16 bits of this register locate the top of the I/O window within a 64-Kbyte page, and the upper 16 bits are a page
register which locates this 64-Kbyte page in 32-bit PCI I/O address space. Bits 15
–
2 are read/write and allow the I/O
limit address to be located anywhere in the 64-Kbyte page (indicated by bits 31
–
16 of the appropriate I/O base
register) on doubleword boundaries.
Bits 31
–
16 are read-only and always return 0s when read. The page is set in the I/O base register. Bits 1
–
0 are
read-only and always return 0s, forcing I/O windows to be aligned on a natural doubleword boundary. Writes to
read-only bits have no effect. The PCI1620 assumes that the lower 2 bits of the limit address are 1s.
These I/O windows are enabled when either the I/O base register or the I/O limit register is nonzero. By default, the
I/O windows are not enabled to pass the first doubleword of I/O to CardBus.
Either the I/O base register or the I/O limit register must be nonzero to enable any I/O transactions.

4.23 Interrupt Line Register
The interrupt line register is a read/write register used by the host software. As part of the interrupt routing procedure,
the host software writes this register with the value of the system IRQ assigned to the function.
