Specific flash locations in any sector do not get erased
If only one or both of the first two words of the last line of a sector in a bank are programmed, an Erase of entire Sector, Mass Erase of device, or toggle mass erase does not erase the flash back to all 1's. The diagram below shows the affected words in Sector 0 and Sector 31 of the lower 512KB of Flash.
Program any other word in the Sector-Bank to allow Sector Erase to work.
Toggle Mass Erase or Mass Erase will still not work.
