The Level 1 version / product information tuple provides the host with the following
information:
• The device supports version 7.1 of the PC Card Specification.
• The Manufacturer String is “CF CARD”
• The Product String is “GENERIC”
The Additional Product Information strings are empty.
The CISTPL_CONFIG tuple provides basic configuration information including the
following:
• Base address of the configuration registers (specified as 0xF8)
• Which configuration registers are present and supported (Configuration
Options Register, Configuration Status Register, Pin Replacement
Register, and Socket and Copy Register are supported).
• Index of the last Configuration Table Entry (set to 0x04).

This tuple specifies one particular configuration that the device can be used in. Each
configuration has an index number, which is used by the host to select it. This
configuration has the following properties:
• Index is 0x01
• READY signal is active, and configuration is for I/O and Memory mode.
• Nominal Vcc is set to be 3.30 volts.
• Requests 16 bytes of I/O space, starting at 0x03F8.
• Level interrupts, interrupt sharing are supported.
• Any interrupt (IRQ0-15) can be used.
• Maximum number of identical cards is set to 8.
This configuration is based on the previous configuration, except that it specifies the
I/O space can start anywhere.
This tuple specifies one particular configuration that the device can be used in. Each
