Fuse Bytes
ATtiny24/44/84
The ATtiny24/44/84 have three fuse bytes.
describe 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.

2. DWEN must be unprogrammed when Lock Bit security is required. See
3. The SPIEN Fuse is not accessible in SPI programming mode.

Fuses. After programming the RSTDISBL fuse, high-voltage serial programming must be used
to change fuses and allow further programming.
