9b. Load Address Byte
9c. Read Signature Byte
10a. Enter Calibration Byte Read
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 Extended byte is listed in Table 99 on page 229.
7. The bit mapping for Fuses High byte is listed in Table 100 on page 230.
8. The bit mapping for Fuses Low byte is listed in Table 101 on page 230.
9. The bit mapping for Lock Bits byte is listed in Table 97 on page 228.
10. Address bits exceeding PCMSB and EEAMSB (Table 106 and Table 107) are don’t care
a = address high bits
b = address low bits
H = 0 – Low byte, 1 – High Byte
o = data out
i = data in
