1. For page sizes less than 256 words, parts of the address (bbbb_bbbb) will be parts of the page address.
2. For page sizes less than 256 bytes, parts of the address (bbbb_bbbb) will be parts of the page address.
3. 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.
