The Flash Program Memory and EEPROM data memory are organized in pages. The pages are
word accessible for the Flash and byte accessible for the EEPROM.
Table 7-2 on page 14
operations are performed on one page at a time, while reading the Flash is done one byte at a
time. For Flash access the Z-pointer (Z[m:n]) is used for addressing. The most significant bits in
the address (FPAGE) give the page number and the least significant address bits (FWORD)
give the word in the page.
Table 7-2.
Table 7-3 on page 14
EEPROM 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 Regis-
ter (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.
