6.13.7 Data EEPROM write enable
The data EEPROM has a Write Enable mechanism to help prevent against inadvertent
writes. If the WE bit (FMCON.6) is set writes to the data EEPROM are enabled. When
cleared, writes are disabled. This bit only affects execution mode. The WE bit is set when:
The disable write enable bit, DISWE (UCFG.2) = 1
In ICP mode
The SET_WE (08H) command is written to FMCON followed by the key value (96H)
being written to FMDATA
The WE bit is cleared following any reset. The WE bit may also be cleared by writing the
CLR_WE (0BH) command to FMCON.
6.13.8 Data EEPROM security bits
The data EEPROM security bits protects each data EEPROM page. The data EEPROM
page security bits and their effects are shown in Table 35.
6.13.9 Summary of data EEPROM commands
Table 37 is a summary of the FMCON commands related to the data EEPROM.

Execution Erase Protect x. When programmed = 1, cannot be erased
with ERS_DP command in execution mode. ERS_DP can be used in
ICP mode.

Page Write Protect x. When programmed = 1, data EEPROM cannot
be erased or programmed using PROG or EP commands.

MOVCx
When programmed = 1, prevents instructions fetched from off-chip
from reading the contents of the data EEPROM and returns FFH.
CRC_DP are disabled if the corresponding Page Write Protect is
disabled.
