    A:

    Note: This answer applies to devices with F05 flash.  Refer to:  [FAQ] F05 Flash: Which C2000 devices have "F05 flash"?

    • Memory locations of each sector are documented in the data manual memory map.
    • A flash bank is divided up into sectors.
    • A sector's size corresponds to the physical architecture of the flash memory and the size can not be changed..
    • A sector is the smallest section of flash that can be erased. For example, you can erase all of sector 'A' but you can not erase a single word in sector A.
    • You can combine sectors in your linker command file to create a larger .text section. This will not change the fact that a sector is the smallest amount that can be erased.
