Reading the Signature Bytes
Reading the Calibration Byte
152
ATmega163(L)
The algorithm for reading the Signature bytes is as follows (refer to Programming the
Flash for details on Command and Address loading):
1. A: Load Command “0000 1000”.
2. C: Load Address Low Byte ($00 - $02).
3. Set OE to “0”, and BS to “0”. The selected Signature byte can now be read at
4. Set OE to “1”.
The algorithm for reading the Calibration byte is as follows (refer to Programming the
Flash for details on Command and Address loading):
1. A: Load Command “0000 1000”.
2. C: Load Address Low Byte, $00.
3. Set OE to “1”.
DATA.
Set OE to “0”, and BS1 to “1”. The Calibaration byte can now be read at DATA.
