Yes Jez that is tomorrow's agenda.
Hate to complain about a pioneering company that "liberated" us from pull outs and second hand 51. But unfortunately Atmel has become pretty lax in India. A couple batches of their chips could be read even after locking, yet they did reply any of my queries on that count. Last year some of their chips showed erratic behaviour in previously tested circuits. The problem went away when we used Philips. Now the Philips folks seem to have taken a shortcut of their own. What is more worrisome is that the chip behaves erratic.
