Reading the Calibration Byte
Parallel Programming
Characteristics
240
ATmega162(V/U/L)
The algorithm for reading the calibration byte is as follows (refer to “Programming the
Flash” on page 234 for details on Command and Address loading):
1. A: Load Command “0000 1000”.
2. B: Load Address Low Byte, 0x00.
3. Set OE to “0”, and BS1 to “1”. The Calibration byte can now be read at DATA.
4. Set OE to “1”.
