Attiny841 vs 441 vs 44A and other questions But just for my knowledge, am I correct to think that I would want a separate line going to the chip to wake it from the sender? Or can the same Rx pin wake it up no problem?
The...

ADC Noise Canceller so nothing can occur to "interrupt" the ADC process
The ADC process isn't interrupted, but the CPU can still be woken up by some other interrupt during the conversion...
Different pull-ups for TWI level shifter Wow, did not know this. Do you know the percentage of pulsed
power versus constant power to achieve the same perceived
brightness? Does it depend on duty cycle and/or...

Clock speed on a atiny13a No the fuse display says it is running at 9.6MHz divided by eight (CKDIV8). That makes 1.2MHz.
So about ten clocks per period would make a 120kHz frequency.
And the...

ATtiny85 Software BOD Disable Where did you find this information in the datasheet (that revision C is the most recent) - the errata?
Yes, I was looking at the errata. And assumed that any newer revision...

ATtiny85 Software BOD Disable Still no.
I'd guess that your troubles in 2014 were caused by a misinterpretation of the chip markings. The datasheet currently on Atmel website (from 2013) lists 'C' as the...

Also, is PB2 your led? Both main and the ISR set it low, I'd...
