Hi

Is it possible to re-program the flash memory of the ST72C334 using the Kanda Keyfob, if the security option has been set to ''No further Read/Write'' in the previous programming?

Hi,

The option byte needs to be written to no protection before any programming can be done.

Once this option is set, the flash will be erased.
