1. A: Load Command “0000 0100
2. Set OE to “0”, BS2 to “0” and BS1 to “0”. The status of the Fuse Low bits can now be
3. Set OE to “0”, BS2 to “1” and BS1 to “1”. The status of the Fuse High bits can now be
4. Set OE to “0”, BS2 to “1”, and BS1 to “0”. The status of the Extended Fuse bits can
5. Set OE to “0”, BS2 to “0” and BS1 to “1”. The status of the Lock bits can now be read
6. Set OE to “1”.
1. A: Load Command “0000 1000
2. B: Load Address Low Byte (0x00 - 0x02).
3. Set OE to “0”, and BS to “0”. The selected Signature byte can now be read at DATA.
