ATmega8535(L)
Table 97. Lock Bit Protection Modes
Notes:
The ATmega8535 has two Fuse bytes. Table 98 and Table 99 describe briefly the func-
tionality of all the fuses and how they are mapped into the fuse bytes. Note that the
fuses are read as logical zero, “0”, if they are programmed.

Memory Lock Bits
1. Program the Fuse bits before programming the Lock bits.
2. “1” means unprogrammed, “0” means programmed.
1. The SPIEN Fuse is not accessible in Serial Programming mode.
2. The CKOPT Fuse functionality depends on the setting of the CKSEL bits. See “Clock
3. The default value of BOOTSZ1..0 results in maximum Boot Size. See Table 93 on
