Fixed several bugs:
- TCB wasn't running. The datasheet steps were not complete.
- TCA was waking the MCU and causing the main program to run. Added checks
to ensure program only runs on button or TCB wakeup.
- Fixed some peculiarities with specific RGBLED programs
misinterpreted docs. too much ARM in my life.
the system sets up the clock divider with /2 and expects it to stay there.
was setting the divider to /1 thinking it only affected peripherals.
adjusted timings to compensate for the new divider.
arduino as a library will not build with -flto. I can't figure it out. so we
waste some space compared to what platformio was building. oh well. there's
still over 1K of space left for programs.
was able to put the button on PA2 and confirm PA1 for the LED data. because we're using PA2 for the button, we have async sleep support and no longer need to do all the button checks and mitigations for the partial-async pin which was used before.
compiled code size is slightly larger after removal of mitigations and other minor fixes...
