To read the Fuse High Byte (FHB), simply replace the address in the Z-pointer with 0x0003 and
repeat the procedure above. If successful, the contents of the destination register are as follows.
Refer to Table 19-4 on page 142 for detailed description and mapping of the Fuse High Byte.
To read the Fuse Extended Byte (FEB), replace the address in the Z-pointer with 0x0002 and
repeat the previous procedure. If successful, the contents of the destination register are as
follows.
Refer to Table 19-3 on page 142 for detailed description and mapping of the Fuse Extended
Byte.
18.6.3
Reading Device Signature Imprint Table from Firmware
To read the contents of the device signature imprint table, follow the below procedure:
1.
Load the Z-pointer with the table index.
2.
Set RSIG and SPMEN bits in SPMCSR.
3.
Issue an LPM instruction within three clock cycles.
4.
Read table data from the LPM destination register.
See program example below.
Note:
If successful, the contents of the destination register are as described in section “Device Signa-
