ATtiny1616 TCB0,1 and EVSYS hookup not working as expected
Hi all, I have TCB0 in timeout mode, linked to a pin input via EVSYS to reset it. If it doesn't get reset the single pulse output gets fed into EVSYS which passes it to TCB1 which...

ATtiny1616 - lowest sleep draw with a comparator on
Sanity check required!   My system is currently at 470uA / 0.5mA, of which 26uA is a boost chip and 11uA a FET controller. I'm willing to say another 50uA in losses...

ATtiny1616 TCDn / TCBn - a blipping challenge
I think you'll like this challenge!     Here we have a buck controller with a floating driver. It's a nice driver except it uses a stupid multi-input technique to save...

ATtiny16** TCBn Frequency Measurement Overflow Handling
Hi,   Another unknown condition not described in the datasheet.   When using a SYSCLK of 250,000, and DIV/2 mode with 65,535 counts the lowest frequency can be...

ATtiny1616 refuses to jump to AC2 vector
I'm baffled by this one! ** please note I have simplified the code, kindly don't offer to change the approach it's done this way for a reason not shown here ** I have the RTC PTC...

ATtiny* Does interrupt flag get set when interrupt disabled?
Quick question, for a peripheral (in this case a comparator / AC) will the flag be set (aka a latch) when interrupt is disabled, or will I have to enable the interrupt and disable...

ATtiny1616 Best Sleep Using AC or Pin Level Detect
I've a circuit which inputs a slowly changing analog sine wave to a pin, where the AC (comparator) level compares it.   I'd like ideally to stick the chip into powerdown...

ATtiny1616 TCD Toggling Outputs Without Timer Disable/Enable
I'm using TCD to generate three 50/50 1MHz PWM signals, all identical. These get output to three pins. I can see how to cause a fault which would place all 4 outputs into a...

ATtiny1616 precision UVLO with timeout using AC, LUT, PIT, TCB
Sanity check required! - is it correct or is there a better way? An external voltage is monitored by comparator, 30ms after it goes low an interrupt is triggered. If at any point...

ATtiny1616 Temperature measurement on ADC1
Hi all,   I can't for the life of me figure out why this isn't working but break-point always shows RES= 0-4. Anything obvious?   VREF.CTRLC =...

Possible to Wake CPU by Interrupt but not to jump to vector?
Say I have the following code   while (1) { //wdt_reset(); if (ADC_READY(USB_CURRENT_ADC)) { USB_Adc(); // read will reset } if (ADC_READY(...

ATtiny1616 - A zerocross "filter" using peripherals
Here goes...   I have a 10-200Hz AC signal going through a high-resistor into an AC, which feeds into a TCB to do frequency measurement. The AC is on low power (long...
