FUNCTION

7–6

Interface type. Bits 7–6, which are hardwired as 10b, identify the 16-bit PC Card support provided by the PCI1031. The

PCI1031 supports both I/O and memory 16-bit PC Cards.

5–4

R/W

Reserved. Bits 5–4 can be used for Intel 82365SL-DF emulation.

3–0

R/W

Intel 82365SL-DF revision. Bits 3–0 store the Intel 82365SL-DF revision supported by the PCI1031. Host software can

read this field to determine compatibility to the Intel 82365SL-DF register set. This field defaults to 0100b upon PCI1031

reset.
