Reading the Signature Bytes
Reading the 8 MHz RC Oscillator Calibration Byte
Reading the Temperature Sensor Parameter Bytes
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 now
5. Set OE to “0”, BS2 to “0” and BS1 to “1”. The status of the Lock bits can now be read at
6. Set OE to “1”.

The algorithm for reading the Signature bytes is as follows (refer to
page 222
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”.
The algorithm for reading the 8 MHz RC Oscillator Calibration byte is as follows (refer to
gramming the Flash” on page 222
1. A: Load Command “0000 1000
2. B: Load Address Low Byte, 0x00.
3. Set OE to “0”, and BS1 to “1”. The 8 MHz RC Oscillator Calibration byte can now be read
4. Set OE to “1”.
The algorithm for reading the Temperature Sensor parameter bytes is as follows (refer to
gramming the Flash” on page 222
