| Zusammenfassung: | The pin definition of a PC card having a plurality of specification modes is changed stepwise in a state that it is mounted in a PC card slot. This realizes mode switching in an active state while preventing the pin functions of the PC card
10
and the PC card slot
20
from conflicting with each other. A standardized mode is employed when the PC card
10
is in the initial state. Information to the effect that the PC card is mode-switchable is written to a special area of the PC card
10
in advance. This makes it possible to use the PC card for general purposes. |
