Write System Zone Command, Write Fuse Byte Option [$c4]
The Write Fuse Byte Option of the Write System Zone command is used to program the security fuses.
The Write Fuse Byte Option of the Write System Zone command programs the security fuses. Once programmed, the
fuses cannot be erased. This operation can be performed in the Normal, Authentication, or Encryption Communication
modes. The fuse byte value is never encrypted. Only PICCs in the Active State are permitted to answer this command.
