Table 16. WriteSpareArea

Function name

WriteSpareArea.

Prototype

uint16_t WriteSpareArea (uint32_t address,

uint8_t *buff)

Behavior description

Page Number in multiple of 512 Byte.

Input parameter

address: Corresponding Page Number of Spare Area to be read.

buff: Pointer to the data to be written in SPARE AREA.

Output parameter

Status of WriteSpareArea. This parameter can be:

– NAND_OK: when Write SPARE AREA is successful.

– NAND_FAIL: when Write SPARE AREA fails to Write.
