INITIALISATION:
MAIN:
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.
