Hi for all of you...
This is the first time I login to this forum, so forgive me some uncorrections that I will certainly make...
I've been working for some time in a project with an MC9S12XDP512 processor. I've been abble to put all the things working on it. AD, SPI, timers, interrupts and so on.
But, and we always have a but, I'm having some troubles with IRQ... Specially with the duration of the pulse on the IRQ pin.
If I send a small pulse to it, sooner or later I'll get a spurious interrupt. If a send a too longer pulse, I'll get it once again.
Does anyone knows where to find some information on timings for this processor?
