ATmega128RFA1
Table 31-5. Fuse Low Byte
The status of the Fuse bits is not affected by Chip Erase. Note that the Fuse bits are
locked if Lock bit1 (LB1) is programmed. Program the Fuse bits before programming
the Lock bits.
The fuse values are latched when the device enters programming mode and changes
of the fuse values will have no effect until the part leaves Programming mode. This
does not apply to the EESAVE Fuse which will take effect once it is programmed. The
fuses are also latched on Power-up in Normal mode.
All Atmel microcontrollers have a three-byte signature code which identifies the device.
This code can be read in both serial and parallel mode, also when the device is locked.

4. Never ship a product with the OCDEN Fuse programmed regardless of the setting
1. The default value of SUT1:0 results in maximum start-up time for the default clock
2. The default setting of CKSEL3:0 results in internal RC Oscillator @ 8 MHz. See
3. The CKOUT Fuse allows the system clock to be output on PORTE7. See

parts of the clock system to be running in all sleep modes. This may increase the
power consumption.
