6.2 Data EEPROM

Data EEPROM consists of 256 bytes of user data memory. The EEPROM provides storage locations for 8-bit user defined data.

EEPROM can be read and/or written through:
  • NVMREG access
  • External device programmer

Additionally, read-only access to the EEPROM contents are also available through indirect addressing via FSR/INDF registers.

Unlike Program Flash Memory, which must be written to by row, EEPROM can be written to byte by byte.
