#73782 - RE: p89v51rd2 secutity bit - serial numb
Responding to: ???'s previous message
from Esacademy flash magic forum
-----------------------------------------------
hi andy.
2.01 works fine.

A small observation:

IF clock bit was previously set and security bit unset

and you select in step 4 of flash magic
verify after programming,
fill unused flash,
set security bit 1,
and 6 clocks/cycle
then flash magic does not set security bit.

You have to select in step 4 of flash magic
verify after programming,
fill unused flash,
set security bit 1,
and "uncheck" 6 clocks/cycle.
Then flash magic sets security bit.

Can flash magic "first read" and then write if a bit is not set?

Regards
Lambros Sirivlis
