Fuse Bits
108
ATtiny26(L)
The ATtiny26 has two Fuse bytes. Table 50 and Table 51 describe briefly the functionality of all
the fuses and how they are mapped into the fuse bytes. Note that the fuses are read as logical
zero, “0”, if they are programmed.
Table 50. Fuse High Byte
Notes:
Table 51. Fuse Low Byte
Notes:
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. When programming the RSTDISBL Fuse, Parallel Programming has to be used to change
1. The default value of SUT1..0 results in maximum start-up time. See Table 12 on page 29 for
2. The default setting of CKSEL3..0 results in internal RC Oscillator at 1 MHz. See Table 3 on
3. The CKOPT Fuse functionality depends on the setting of the CKSEL bits. See “System Clock
