NANDFLASH-CTRL_SD - NAND Flash Memory Controller Software Driver

NANDFLASH-CTRL_SD.PNG

The NANDFLASH-CTRL_SD Software Driver was designed to provide user’s application with full functionality of the NANDFLASH-CTRL NAND Flash Controller IP core.

The driver supports a whole scope of NAND Flash related functions: program memory page, read memory page and erase memory block.

Furthermore, the driver supports additional NAND Flash controller functionalities like DMA transmission, hardware mapping of memory blocks and selecting memory read-only area. It also allows software configuration of hardware ECC (Error Correction Code) settings.
