Reading the
Calibration Byte
Parallel Programming
Characteristics

ATtiny2313
The algorithm for reading the Calibration byte is as follows (refer to
page 165
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”.
