285 / 357 page ![]() 285 2466S–AVR–05/09 ATmega16(L) Notes: 1. This command sequence is not required if the seven MSB are correctly set by the previous command sequence (which is normally the case). 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 Table 105 on page 260 7. The bit mapping for Fuses Low byte is listed in Table 106 on page 261 8. The bit mapping for Lock bits byte is listed in Table 103 on page 259 9. Address bits exceeding PCMSB and EEAMSB (Table 107 and Table 108) are don’t care 10b.
