If I want to count input pulses with the TCA0 counter, I write:

I do not know the processor you use? So i tried some updi processor and indeed the option is not recognized while it is present in the DAT file.
So it seems this is a bug in the explorer. I will check it later and update this topic.

I also like the Code Explorer warnings because they work "on the go" and prevent to make long term mistakes on the code.
Another theme is that I sometimes wrote that "Baud3 for Mega2560" is "undeclared", the same way
"__readrampz" used by NETZMAN is undeclared too, same "Spi1move". Very Happy

Im patient and wait when Mark add this into the Code Explorer syntax Very Happy

To Mark
I tested it with Attiny412 and Attiny3226.
I think that the same is also with AVR128DB48, but Im not sure.

The problem is that you did not defined the mode for the timer which is mandatory but not mentioned in the help.
So your code should start with Config Tca0 = Normal ,RESOLUTION=NORMAL followed by the other options. This because the parameters for the 2 modes are different depending on the mode. Whenever the DAT file contains a reference to PARENTOPTION and PARENTVALUE it is important that this parent is defined.

example:
OPTION6=EVENT_ACTIONA
OPTION6VALUE=[DISABLED,ENABLED,COUNT_POS_EDGE,COUNT_ANY_EDGE,COUNT_HIGH_LVL,COUNT_UPDOWN]
OPTION6PARENT=OPTION5
OPTION6PARENTVALUE=NORMAL

Also notice that some processors use EVENT_ACTION, but those with multiple actions use EVENT_ACTIONA and EVENT_ACTIONB

Great,
Mark, thanks a lot for the explanation.
Event_ActionA and Event_actionB, that's exactly the case with the Attiny3226 I'm testing here.
I was almost sure I saw it in the configuration menu when I was playing with it a few days ago. And I couldn't figure out why it stopped showing.
Finally I was thinking it was some other timer/counter. Resolution = Normal has zero in the register, so I assumed it is the default, no need to set it.

By the way, how is it possible that it compiled and worked correctly even if I had the wrong syntax?
Event_action without "A".

Yes for the compiler because it is zero you do not need to set it. But the Code Explorer has different options in some cases. And the options are connected to such an option.
Without that you chose one the options are not visible.
The reason it compiles is that the compiler accepts both event_action and event_actionA as the same thing.
