The Flash Program Memory and EEPROM data memory is 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 the time, while reading the Flash is done one byte at
the 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.
Table 7-3 on page 14
EEEPROM 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)
gives the page number and the least significant address bits (E2BYTE) gives the byte in the
page.
