ATmega128RFA1
2. C: Load Data Low Byte. Bit n = “0” programs and bit n = “1” erases the Fuse bit.
3. Give WR
The algorithm for programming the Fuse High bits is as follows (refer to
the Flash" on
1. A: Load Command “0100 0000”.
2. C: Load Data Low Byte. Bit n = “0” programs and bit n = “1” erases the Fuse bit.
3. Set BS2, BS1 to “01”. This selects high data byte.
4. Give WR
5. Set BS2, BS1 to “00”. This selects low data byte.
The algorithm for programming the Extended Fuse bits is as follows (refer to
"Programming the Flash" on
1. A: Load Command “0100 0000”.
2. C: Load Data Low Byte. Bit n = “0” programs and bit n = “1” erases the Fuse bit.
3. Set BS2, BS1 to “10”. This selects extended data byte.
4. Give WR
5. Set BS2, BS1 to “00”. This selects low data byte.

The algorithm for programming the Lock bits is as follows (refer to
Flash" on
1. A: Load Command “0010 0000”.
2. C: Load Data Low Byte. Bit n = “0” programs the Lock bit. If LB mode 3 is active
3. Give WR
The Lock bits can only be cleared by executing Chip Erase.
(LB1 and LB2 are programmed), it is not possible to program the Boot Lock bits by
any External Programming mode.
