Latching of Fuses
2486Z–AVR–02/11
Table 88. 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.
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.
