DATA EEPROM
(Cont’d)
6.4 POWER SAVING MODES
Wait mode
The DATA EEPROM can enter WAIT mode on ex-
ecution of the WFI instruction of the microcontrol-
ler. 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.
Halt mode
The DATA EEPROM immediatly 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.
6.5 ACCESS ERROR HANDLING
If a read access occurs while LAT=1, then the data
bus will not be driven.
If a write access occurs while LAT=0, then the
data on the bus will not be latched.
If a programming cycle is interrupted (by software/
RESET action), the memory data will not be guar-
anteed.
