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. When the
EE_WRITE routine detects a different data size from the size set up in the
previous operation, the operation will not be executed. However in some
situations, the routine cannot detect incorrect data size. The user must
ensure that data size is same as the previous operation whenever this
routine is executed.
