Reading the Calibration Byte
Parallel Programming Characteristics
The algorithm for reading the Calibration byte is as follows (refer to
on page 305
Figure 25-7. Parallel Programming Timing, Including some General Timing Requirements
Figure 25-8. Parallel Programming Timing, Loading Sequence with Timing Requirements
Note:
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”.
