The coding example below uses the $EE00–$EFFF page for data storage. The data array size is 15
bytes, and the bus speed is 4.9152 MHz. The coding assumes the data block is already loaded in RAM,
with the address pointer, FILE_PTR, pointing to the first byte of the data block.

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 7 to 15. If the FLASH page
is already programmed with a data array with a different size, the
EE_WRITE call will be ignored.
