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.
