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