Similarly, when reading the Fuse High byte (FHB), load 0x0003 in the Z-pointer. When an LPM
instruction is executed within three cycles after the BLBSET and SELFPRGEN bits are set in the
SPMCSR, the value of the Fuse High byte will be loaded in the destination register as shown
below. See
byte.
Similarly, when reading the Extended Fuse byte (EFB), load 0x0002 in the Z-pointer. When an
LPM instruction is executed within three cycles after the BLBSET and SELFPRGEN bits are set
in the SPMCSR, the value of the Extended Fuse byte will be loaded in the destination register as
shown below. See
Fuse byte.
Fuse and Lock bits that are programmed, will be read as zero. Fuse and Lock bits that are
unprogrammed, will be read as one.
