FAT driver routines provide operations to read, write, and initialize drives that support the FAT file system. FAT Driver routines are not reentrant.
| Routine | Description |
|---|---|
| Init | Initializes the FAT Drive. |
| UnInit | Uninitializes the FAT Drive. |
| ReadSect | Reads sectors from FAT Drive. |
| WriteSect | Writes sectors to FAT Drive. |
| ReadInfo | Reads the configuration info from the FAT Drive. |
| CheckMedia | Checks the FAT Drive media status (Card Inserted, Write Protected). |
