Flash and EEPROM Page Size
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 shows the Flash Program Memory organization. Flash write and erase
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) gives the page number and the least significant address bits (FWORD)
gives the word in the page.
Table 7-2.
Number of words and Pages in the Flash.
Table 7-3 on page 14 shows EEPROM memory organization for the XMEGA A3 devices. EEE-
PROM 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) gives
the page number and the least significant address bits (E2BYTE) gives the byte in the page.
