The EE_WRITE routine is unable to check for incorrect data blocks, such
as the FLASH page boundary address and data size. It is the responsibility
of the user to ensure the starting address indicated in the data block is at
the FLASH page boundary and the data size is 2 to 15. If the FLASH page
is already programmed with a data array with a different size, the
EE_WRITE call will be ignored.
