The EEPROM is written page-wise. But only the bytes that are loaded into the page are actually written to the EEPROM. Page-
wise EEPROM access is more efficient when multiple bytes are to be written to the same page. Note that auto-erase of
EEPROM is not available in High-voltage Serial Programming, only in SPI Programming.

The loaded command and address are retained in the device during programming. For efficient
programming, the following should be considered.
The Chip Erase will erase the Flash and EEPROM
not reset until the Program memory has been completely erased. The fuse bits are not changed.
A Chip Erase must be performed before the Flash and/or EEPROM are re-programmed.
Note:
• The command needs only be loaded once when writing or reading multiple memory
• Skip writing the data value 0xFF that is the contents of the entire EEPROM (unless the
