Table 7-2.
Table 7-3 on page 14
EEPROM write and erase operations can be performed one page or one byte at the time, while
reading the EEPROM is done one byte at the 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.
