1. A: Load Command “0000 0011”
2. G: Load Address High Byte (0x00 - 0xFF)
3. B: Load Address Low Byte (0x00 - 0xFF)
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
3. Give WR a negative pulse and wait for RDY/BSY to go high
1. A: Load Command “0100 0000”
2. C: Load Data Low Byte. Bit n = “0” programs and bit n = “1” erases the Fuse bit
3. Set BS1 to “1” and BS2 to “0”. This selects high data byte
4. Give WR a negative pulse and wait for RDY/BSY to go high
5. Set BS1 to “0”. This selects low data byte
1. A: Load Command “0100 0000”
2. C: Load Data Low Byte. Bit n = “0” programs and bit n = “1” erases the Fuse bit
3. Set BS1 to “0” and BS2 to “1”. This selects extended data byte
4. Give WR a negative pulse and wait for RDY/BSY to go high
5. Set BS2 to “0”. This selects low data byte
