Power saving modes
Wait mode
The DATA EEPROM can enter Wait mode on execution of the WFI instruction of the
microcontroller 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
instruction. Therefore the EEPROM will stop the function in progress, and data may be
corrupted.
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 integrity of the data in
memory will not be guaranteed.
