The TC function in UC3 is just not as good as it was in AVR

guys,

you got to believe this. the function of TC on new UC3 is just bad...

for example, the new TC don't let you have RA/RB/RC compare intrrupt in the capture mode, but the old AVR do.

'old AVR' == AVR8??

I agree the TC is a little limited, mainly in resolution etc. But hopefully all will be better. After all, it took what, 10 years for them to get the AVR8 to it's peak (IMHO), the mega128.

-S.

Well, those are the first chips in the series. Can't get perfect and everything in the start... Well, you can, but it would be a coincidence or brilliance on the side of the company.

There are pointy haired bald people.
Time flies when you have a bad prescaler selected.

The TC in the UC3 (and ap7) is the same one that has been used in the AT91 series, unchanged for many years now. I never much liked it there either. Perhaps Atmel will finally provide something more reasonable. What most immediately hurts my own usage is the lack of resolution (32 bit CPUs need 32 bit counters, especially at tens-of-MHz rates!) but compared to the avr8 TC modules I can see there are a lot of other things needed by more "micro" oriented applications.
