Revision A has not been sampled.
Wrong values read after Erase Only operation
Parallel Programming does not work
Watchdog Timer Interrupt disabled
EEPROM can not be written below 1.9 volts
At supply voltages below 2.7 V, an EEPROM location that is erased by the Erase Only oper-
ation may read as programmed (0x00).
Problem Fix/Workaround
If it is necessary to read an EEPROM location after Erase Only, use an Atomic Write opera-
tion 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 loca-
tion 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 serially.
If the watchdog timer interrupt flag is not cleared before a new timeout occurs, the watchdog
will be disabled, and the interrupt flag will automatically be cleared. This is only applicable in
interrupt only mode. If the Watchdog is configured to reset the device in the watchdog time-
out following an interrupt, the device works correctly.
Problem fix / Workaround
Make sure there is enough time to always service the first timeout event before a new
watchdog timeout occurs. This is done by selecting a long enough time-out period.
Writing the EEPROM at V
Problem fix / Workaround
Do not write the EEPROM when V
In-System Programming disabled (SPIEN unprogrammed)
Reset Disabled (RSTDISBL programmed)
CC
below 1.9 volts might fail.
CC
is below 1.9 volts.
