Watchdog Timer Interrupt disabled

Writing the EEPROM at V
Problem Fix/Workaround
Do not write the EEPROM when V
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.
Writing to any of these locations and bits may in some occasions fail.
Problem Fix/Workaround
After a writing has been initiated, always observe the RDY/BSY signal. If the writing should
fail, rewrite until the RDY/BSY verifies a correct writing. This will be fixed in revision D.
Special combinations of fuse bits will lock the device for further programming effectively
turning it into an OTP device. The following combinations of settings/fuse bits will cause this
effect:
– 128 kHz internal oscillator (CKSEL[1..0] = 11), shortest start-up time
– 9.6 MHz internal oscillator (CKSEL[1..0] = 10), shortest start-up time
(SUT[1..0] = 00), Debugwire enabled (DWEN = 0) or Reset disabled RSTDISBL = 0.
(SUT[1..0] = 00), Debugwire enabled (DWEN = 0) or Reset disabled RSTDISBL = 0.
CC
below 1.9 volts might fail.
CC
is below 1.9 volts.
