4. Set bits to “0” to program the corresponding lock bit, “1” to leave the lock bit
unchanged.
5. “0” = programmed, “1” = unprogrammed.
6. a = address high byte; b = address low byte; i = data in; o = data out; 1 = lock bit 1; 2
= lock bit 2; 3 = Boot Lock Bit01;
4 = Boot Lock Bit02; 5 = Boot Lock Bit11; 6 = Boot Lock Bit12; 7 = CKSEL0 Fuse; 8 =
CKSEL1 Fuse ; 9 = CKSEL2 Fuse;
A = CKSEL3 Fuse; B = BODEN Fuse; C = BODLEVEL Fuse; D = BOOTRST Fuse; E
= BOOTSZ0 Fuse; F = BOOTSZ1 Fuse; G = EESAVE Fuse; H = JTAGEN Fuse; I =
OCDEN Fuse
