My New Favorite Switching Power Supply IC
That is indeed a nice part.  Thanks for sharing.   In fact you've inspired me to share a couple of nice switchers too.  Namely LT8650S and LT8609S.   Both are...

How would I efficiently measure multiple cell voltages of my own supply?
For easier prototyping, this link may be handy...   SiliconChip Mag, March 2016, Battery Pack Cell Balancer   You'll only get "preview" level access but you should be...

How would I efficiently measure multiple cell voltages of my own supply?
Oh there are some fun devices out there for this sort of application. Here are some part numbers and app notes that may be helpful.   Texas Instruments: bq76PL455A-Q1,...

Timer Interrupt on XMEGA32e5
I would have thought an extern volatile uint16_t count;in the file that contains the ISR should do the trick but you said you tried that.   Normally (in my way of thinking)...

Datasheet Interpretation - E5 32kHz Oscillator
So I ran my little clock module over night (one that was a balmy 25 deg.C fortunately) and I ended up about 5 secs fast. Can't recall how many hrs I said it was but the quick calc...

Datasheet Interpretation - E5 32kHz Oscillator
@ Kabasn & Chapman: I had looked at AN2648 and this is what lead me to believe the total load cap is a little high.   I can't find the specified xtal PN for that Mattair...

32768Hz Crystal... 100ms ticks possible?
If your hardware is not locked down, are you aware that watch crystals are available in 32.000kHz?   32000 / 128 / 25 = 10Hz -> OCR2A = 24.   Also 32000 / 128 / 250...
