5 ExCA Compatibility Registers (Functions 0 and 1)
The ExCA registers implemented in the PCI1520 are register-compatible with the Intel 82365SL
–
DF PCMCIA
controller. ExCA registers are identified by an offset value that is compatible with the legacy I/O index/data scheme
used on the Intel 82365 ISA controller. The ExCA registers are accessed through this scheme by writing the register
offset value into the index register (I/O base) and reading or writing the data register (I/O base + 1). The I/O base
address used in the index/data scheme is programmed in the PC Card 16-bit I/F legacy-mode base address register
(PCI offset 44h, see Section 4.28), which is shared by both card sockets. The offsets from this base address run
contiguously from 00h to 3Fh for socket A, and from 40h to 7Fh for socket B. See Figure 5

1. ExCA Register Access Through I/O
The TI PCI1520 also provides a memory-mapped alias of the ExCA registers by directly mapping them into PCI
memory space. They are located through the CardBus socket/ExCA base-address register (PCI offset 10h, see
Section 4.12) at memory offset 800h. Each socket has a separate base address programmable by function. See
Figure 5

844h for both functions
0 and 1. This illustration also identifies the CardBus socket register mapping, which is mapped into the same 4-K
window at memory offset 00h.
