Table 7-3 shows EEPROM memory organization. EEEPROM write and erase operations can be
performed one page or one byte at a time, while reading the EEPROM is done one byte at a
time. For EEPROM access the NVM address register (ADDR[m:n]) is used for addressing. The
most significant bits in the address (E2PAGE) give the page number and the least significant
address bits (E2BYTE) give the byte in the page.
