Programming the Fuse Low Bits

The algorithm for programming the Fuse Low bits is as follows (Please refer to Programming the Flash for details on Command and Data loading):

  1. 1.Step A: Load Command “0100 0000”.
  2. 2.Step C: Load Data Low Byte. Bit n = “0” programs and bit n = “1” erases the Fuse bit.
  3. 3.Set BS1 and BS2 to “0”.
  4. 4.Give WR a negative pulse and wait for RDY/BSY to go high.
