DATA EEPROM (Cont’d)
5.4 POWER SAVING MODES
Wait mode
The DATA EEPROM can enter WAIT mode on ex-
ecution of the WFI instruction of the microcontrol-
ler or when the microcontroller enters Active-HALT
mode.The DATA EEPROM will immediately enter
this mode if there is no programming in progress,
otherwise the DATA EEPROM will finish the cycle
and then enter WAIT mode.
Active-Halt mode
Refer to Wait mode.
Halt mode
The DATA EEPROM immediately enters HALT
mode if the microcontroller executes the HALT in-
struction. Therefore the EEPROM will stop the
function in progress, and data may be corrupted.

5.5 ACCESS ERROR HANDLING
If a read access occurs while E2LAT=1, then the
data bus will not be driven.
If a write access occurs while E2LAT=0, then the
data on the bus will not be latched.
If a programming cycle is interrupted (by a RESET
action), the memory data will not be guaranteed.
5.6 Data EEPROM Read-out Protection
The read-out protection is enabled through an op-
tion bit (see
When this option is selected, the programs and
data stored in the EEPROM memory are protected
against read-out (including a re-write protection).
In Flash devices, when this protection is removed
by reprogramming the Option Byte, the entire Pro-
gram memory and EEPROM is first automatically
erased.
Note: Both Program Memory and data EEPROM
are protected using the same option bit.
