B: The EEPROM array is programmed one page at a time. The Memory page is
loaded one byte at a time by supplying the 2 LSB of the address and data together with
the Load EEPROM Memory Page instruction. The EEPROM Memory Page is stored
by loading the Write EEPROM Memory Page Instruction with the 4 MSB of the
address. When using EEPROM page access only byte locations loaded with the Load
