If successful, the contents of the destination register are as follows. Refer to Table 19-4 on page 140 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 140 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: See “Code Examples” on page 6. If successful, the contents of the destination register are as described in section “Device Signa- ture Imprint Table” on page 141.
