| * \section Purpose | |
| * | |
| * The AMD %norflash Low-level driver code implement procedures to program | |
| * basic operations described AMD-specified command set flash devices. | |
| * The various commands recognized by the devices are listed in the Commands | |
| * Tables provided in the corresponding AMD command set compatible flash | |
| * datasheets. All operation functions are blocked, they wait for the | |
| * completion of an operation by polling the status register. | |
| * | |
| * \section Usage | |
| * -# Flash program using AMD_Write_Data(). | |
| * - The Program command is used to modify the data stored at the | |
| * specified device address. Programming can only change bits | |
| * from ¡®1¡¯ to ¡®0¡¯. It may be necessary to erase the block before | |
| * programming to addresses within it. Programming modifies a single | |
| * Word at a time using static function amd_Program(). Programming | |
| * larger amounts of data must be done in one Word at a time by | |
| * giving a Program command, waiting for the command to complete, | |
| * giving the next Program command and so on. | |
| * -# erase a block within the flash using AMD_EraseSector(). | |
| * - Flash erase is performed on a block basis. An entire block is | |
| * erased each time an erase command sequence is given. | |
| * -# erase whole blocks within the flash using AMD_EraseChip(). | |
| * -# AMD_Reset() function can be issued, between Bus Write cycles | |
| * before the start of a program or erase operation, to return the | |
| * device to read mode. | |
| * -# AMD_ReadDeviceID() is used to retrieve information | |
| * about the Flash Device type. | |
| * -# AMD_ReadManufactoryId() is used to retrieve information | |
| * about the Flash Device Manufactory ID. | |
