5.1 ExCA Identification and Revision Register
The ExCA identification and revision register provides host software with information on 16-bit PC Card support and
Intel 82365SL-DF compatibility. This register is read-only or read/write, depending on the setting of bit 5
(SUBSYSRW) in the system control register (see Section 4.29). See Table 5–2 for a complete description of the
register contents.

Interface type. These bits, which are hardwired as 10b, identify the 16-bit PC Card support provided by the
PCI1410. The PCI1410 supports both I/O and memory 16-bit PC cards.

Intel 82365SL-DF revision. This field stores the Intel 82365SL-DF revision supported by the PCI1410. Host
3–0 365REV R/W software can read this field to determine compatibility to the Intel 82365SL-DF register set. Writing 0010b to
this field puts the controller in 82365SL mode. This field defaults to 0100b upon PCI1410 reset.
