Fuse Bytes
The ATtiny43U has three Fuse bytes. Table 19-3, Table 19-4 and Table 19-5 briefly 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..
Notes:
1. Enables SPM instruction. See “Self-Programming the Flash” on page 135.
Notes:
1. See “Alternate Functions of Port B” on page 75 for description of RSTDISBL and DWEN
Fuses. When RSTDISBL fuse has been programmed, parallel programming must be used for
unprogramming the fuse and programming the device.
2. DWEN must be unprogrammed when Lock Bit security is required. See “Program And Data
3. The SPIEN Fuse is not accessible in SPI Programming mode.
