Instruction
10b. Load Address Byte
10c. Read Calibration Byte
11a. Load No Operation Command
1. This command sequence is not required if the seven MSB are correctly set by the previous command sequence (which is
2. Repeat until o = “1”.
3. Set bits to “0” to program the corresponding fuse, “1” to unprogram the fuse.
4. Set bits to “0” to program the corresponding lock bit, “1” to leave the lock bit unchanged.
5. “0” = programmed, “1” = unprogrammed.
6. The bit mapping for Fuses High byte is listed in
7. The bit mapping for Fuses Low byte is listed in
8. The bit mapping for Lock bits byte is listed in
9. Address bits exceeding PCMSB and EEAMSB
normally the case).
