FLASH API Module
Description Writes data to the Flash address (locator) from a source address (src).
This function is limited by the page length of the Flash memory.
Note: This function does not affect unspecified segments of Flash. For
example, altering the lower half of a page of Flash memory does not
change the value of the upper half page.

- Locator contains 32-bit address of Flash location
-FLASH_START_ADDR is 0x9000000
- Flash address range: 0x90000000 to 0x90020000
- FLASH_PAGE_SIZE = 0x80: 128 bytes
- Page number range: 0 to 1023
-FLASH_PAGE_ADDR(x) = FLASH_START_ADDR +
x*FLASH_PAGE_SIZE )
- If the source address begins in the middle of a page, the write will
invalidate all other data on the page.
Example To write from writeBuffer to pages 1 and 2:
char writeBuffer[FLASH_PAGE_SIZE*2];
FLASH_write((Uint32)writeBuffer,
FLASH_PAGE_ADDR(1),
FLASH_PAGE_SIZE * 2);
