Thank you all, who answered my last message, and now I have other questions
In fact I really need to get the maximum free timer-counters of the board,
since I need a pretty fast measurement rate of signals.(PWM)
Anyone knows, wich features are compromised disabling the microsecond timer?
So the "clock ticks" I would expect from ecos in this case would be maximum
the MCK/2 that TC0 supports?
And a final question, since the Interrupt model that eCos uses as the
documentation says, is based on the ARM model, should I expect that the
interrupt model work would be transparent from ecos code?(On the AT91EB40a).
