Reading the Fuse and Lock Bits
Reading the Signature Bytes
The algorithm for reading the Fuse and Lock bits is as follows (refer to
Flash” on page 256
Figure 4-103. Mapping Between BS1, BS2 and the Fuse and Lock Bits During Read
The algorithm for reading the Signature bytes is as follows (refer to
on page 256
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.
4. Set OE to “1”.
