Table 7-2. Number of words and pages in the flash TBD.
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.
