I/O states pre-POR
12.3.2.1.1 Power-On Reset (POR) The POR is activated when Vdd rises until it reaches the POR threshold voltage.   Microchip technical support confirmed it. Sorry for the...

I/O states pre-POR
"It would seem to me, that POR is a state you are in up until the POR threshold, and when in POR state you get 'reset' logic."   I think you're right.  Vpor is the...

I/O states pre-POR
"That still doesn't answer, or solve the question above."  I've found a reset generator that is guaranteed to work when Vcc is only 0.8 volts.  Or I could just use a...

Thanks.  I'll try not to worry.  But I was bitten before.  I'll probably add an external reset circuit if I can't get a solid answer from MicroChip.

I appreciate your feedback.  But since as Vdd rises "one of the things it does is reset all the IO registers to their power-up state, ie inputs.", you've got to...

Yes, the XNANO board works as a programmer.  I removed the ATtiny416 from the NANO and ran a three wire cable to my target header.  Voila!  It still debugs, too,...

I've got an ATtiny416-XNANO board that works great with AS7. I wonder if I could just remove the ATtiny416 from that board and run a 3 wire (+5V, Gnd, and UPDI) connection from...

The SNAP doesn't appear in the context menus for PIC devices; it only shows up when I select an Atmel uC.  So I give up.  What's my next best option?  Is there a...

MPLAB recognizes the SNAP board and it knows I'm using the ATtiny416, so maybe the problem isn't the firmware in the SNAP.  Attached is the error I have always been getting...

Here's a shot of my MPLAB screen.  What do I click on?

I downloaded IDE 5.35 yesterday, but I didn't know that I needed the IPE.  (I'm just programming in assembler, and I thought the IPE was some kind of fancy C++ framework.)...

Thanks. I misunderstood.  I thought I was doing these things with MPLABX.
