Teensy4 IntervalTimer Channels Problem

[quadrupel]

@Quadrupel - where did you insert the startup patch in startup.c - that is a VERY busy file - don't want to break it. Also - I'm keeping a copy of the original..

I stuck it in the resetHandler function.
Because, I don't like modifying core files, and until there's a production fix to IntervalTimer, I'm putting the fix into the beginning of setup(). It works, and the appropriate comments identify why it's included in the code.

Thanks for the update. I took a look at the change in startup.c. Interesting that it was PIT channel three causing the problem.

Update: i was looking at a file showing changes only and it didn't show the entire fix. I see the fix is actually your entire recommendation.

There may be an issue with the PIT fix in startup.c for 1.48-beta1, see
