Hi Peter,

My idea is not my idea, infact I copied some one else's idea from previous postings.

How about working between 5.0 and 5.1 msec, say 5.05 msec. etc. switch off the micro when only the security bits have been erased.

The more we discuss it, more we cut the brach of tree we are sitting on. (Sanjeev is right)

Let's discourage this concept, its against copy right.
