Reading the Flash
Reading the EEPROM
Programming the Fuse Low Bits
Figure 26-4. Programming the EEPROM Waveforms
The algorithm for reading the Flash memory is as follows (refer to
page 272
The algorithm for reading the EEPROM memory is as follows (refer to
on page 272
The algorithm for programming the Fuse Low bits is as follows (refer to
on page 272
1. A: Load Command “0000 0010”.
2. G: Load Address High Byte ($00 - $FF)
3. B: Load Address Low Byte ($00 - $FF)
4. Set OE to “0”, and BS1 to “0”. The Flash word low byte can now be read at DATA.
5. Set BS1 to “1”. The Flash word high byte can now be read at DATA.
6. Set OE to “1”.
1. A: Load Command “0000 0011”.
2. G: Load Address High Byte ($00 - $FF)
3. B: Load Address Low Byte ($00 - $FF)
4. Set OE to “0”, and BS1 to “0”. The EEPROM Data byte can now be read at DATA.
5. Set OE to “1”.
1. A: Load Command “0100 0000”.
2. C: Load Data Low Byte. Bit n = “0” programs and bit n = “1” erases the Fuse bit.
