B: The EEPROM array is programmed one page at a time. The Memory page is
loaded one byte at a time by supplying the 6 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 7 MSB of the
address. When using EEPROM page access only byte locations loaded with the
Load EEPROM Memory Page instruction is altered. The remaining locations remain
unchanged. If polling (RDY/BSY) is not used, the used must wait at least t
