Indicates a dead battery on the PC Card. This event is signaled through the BVD1 pin, which can be accessed through the pin replacement register (PRR), also. |
CE_BATTERY_LOW |
Indicates a low battery on the PC Card. This event is signaled through the BVD2 pin, which can be accessed through the PRR, also. |

Indicates that a PC Card has changed from a busy to a ready state. |
CE_CARD_REMOVAL |
Indicates that a PC Card has been removed from the socket. |
CE_CARD_UNLOCK |
