RESET +12V
Set OE to “0”, and BS1 to “0”. The EEPROM Data byte can now be read at DATA.
Set OE to “1”.
A: Load Command “0100 0000”.
C: Load Data Low Byte. Bit n = “0” programs and bit n = “1” erases the Fuse bit.
Give WR a negative pulse and wait for RDY/BSY to go high.
A: Load Command “0100 0000”.
C: Load Data Low Byte. Bit n = “0” programs and bit n = “1” erases the Fuse bit.
Set BS1 to “1” and BS2 to “0”. This selects high data byte.
Give WR a negative pulse and wait for RDY/BSY to go high.
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.
