7.7
Data EEPROM memory has its own code-protect bits
in Configuration Words. External read and write
operations are disabled if either of these mechanisms
are enabled.
The microcontroller itself can both read and write to the
internal data EEPROM, regardless of the state of the
code-protect Configuration bit. Refer to Section 19.0
“Special Features of the CPU” for additional
information.

7.8
The data EEPROM is a high-endurance, byte
addressable array that has been optimized for the
storage of frequently changing information (e.g.,
program variables or other data that are updated
often). Frequently changing values will typically be
updated more often than specification D124 or D124A.
If this is not the case, an array refresh must be
performed. For this reason, variables that change
infrequently (such as constants, IDs, calibration, etc.)
should be stored in Flash program memory.
A simple data EEPROM refresh routine is shown in
Example 7-3.

If data EEPROM is only used to store
constants and/or data that changes rarely,
an array refresh is likely not required. See
specification D124 or D124A.
