The SPEC itself, doesn't define the timeout, except for specific commands, also the current 'undefined' number is born in air, I wonder if you can provide the reference as well. If I would suggest to shorten the number that would maybe a problem for other implementation, but I don't see how the increase in timeout is adverse another implementations. Key generation is computational intensive task because of generation of a prime number, so this is really dependent on device capabilities, so there is no better source of definition that HW itself. Thanks Tomas
