Note:
Table 36. Fuse Low Byte
Note:
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.

1. The SPIEN Fuse is not accessible in serial programming mode.
2. The default value of BOOTSZ1..0 results in maximum Boot Size. See Table 29 on page 229
3. See “Watchdog Timer Control Register - WDTCSR” on page 56 for details.
4. Never ship a product with the DWEN Fuse programmed regardless of the setting of Lock bits
1. The default value of SUT1..0 results in maximum start-up time for the default clock source.
2. The default setting of CKSEL3..0 results in internal RC Oscillator @ 8 MHz. See Table 3 on
3. The CKOUT Fuse allow the system clock to be output on PORTC7. See “Clock Output Buffer”
4. See “System Clock Prescaler” on page 33 for details.
