6.8 Card Information Structure
The card information structure (CIS) in the OXCFU950 is normally sourced from the integral EEPROM,
and the OXCFU950 is usually shipped with a standard pre-programmed CIS image, which is documented
in Section 6.8.2. When the EEPROM image is invalid, or when the CIS_Mode pin is asserted, the CIS
defaults to a fixed default CIS image, which is documented in Section 6.8.1. Both the default CIS Image
and the standard pre-programmed CIS image support multi-function operation.
