• Parallel Programming does not work
1. Wrong values read after Erase Only operation
2. Parallel Programming does not work
Wrong values read after Erase Only operation
At supply voltages below 2.7 V, an EEPROM location that is erased by the Erase
Only operation may read as programmed (0x00).
Problem Fix/Workaround
If it is necessary to read an EEPROM location after Erase Only, use an Atomic Write
operation with 0xFF as data in order to erase a location. In any case, the Write Only
operation can be used as intended. Thus no special considerations are needed as
long as the erased location is not read before it is programmed.
Parallel Programming is not functioning correctly. Because of this, reprogramming
of the device is impossible if one of the following modes are selected:
–
–
Problem Fix/Workaround
Serial Programming is still working correctly. By avoiding the two modes above, the
device can be reprogrammed.
In-System Programming disabled (SPIEN unprogrammed)
Reset Disabled (RSTDISBL programmed)
