22.7.13 Reading the Signature Bytes

The algorithm for reading the Signature bytes is as follows (refer to ”Programming the Flash” on

page 174 for details on Command and Address loading):

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”.

22.7.14 Reading the Calibration Byte

The algorithm for reading the Calibration byte is as follows (refer to ”Programming the Flash” on

page 174 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”.
