Fuse bits
High byte
Table 30-2.
Notes:
The Atmel ATmega16HVB/32HVB has two Fuse bytes.
describe briefly the functionality of all the fuses and how they are mapped into the Fuse byte.
Note that the fuses are read as logical zero, “0”, if they are programmed.

Memory lock bits
1. Program the Fuse bits and Boot Lock bits before programming the LB1 and LB2.
2. “1” means unprogrammed, “0” means programmed.
1. The fuse controls the initial value of the System Clock prescaler, see
2. The default value of BOOTSZ1:0 results in maximum Boot Size.
