* \section Purpose | |
* | |
* The INTERL %norflash Low-level driver code implement procedures to program | |
* basic operations described INTEL-specified command set flash devices. | |
* The various commands recognized by the devices are listed in the Commands | |
* Tables provided in the corresponding INTEL 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 INTEL_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 intel_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 INTEL_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 INTEL_EraseChip(). | |
* -# INTEL_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. | |
* -# INTEL_ReadDeviceID() is used to retrieve information | |
* about the Flash Device type. | |
* -# INTEL_ReadManufactoryId() is used to retrieve information | |
* about the Flash Device Manufactory ID. | |
