I got it working.I can set or clear a bit, and make it flow through the register hierarchy.
The code I posted earlier in the comment is OK, and when I set up the right enable flags, the OPERATION bit in the STATUS BYTE is set.

Set that OPERATIONS bit in status byte is enabled:
*SRE #H80

Set that bit 0 of the OPERATIONS register (the one I use for digital in event capture) causes u push up to STATUS register
STAT:OPERation:ENABle #H01

I documented before how I enable the user register bit 5 (a random choice) to capture a (faked) digital in pin 0 status change, and let it trickle through to OPERATIONS bit 0.

i see CFG_TUD_USBTMC_ENABLE_INT_EP is on, however i do nor see how would we tickle the interrupt endpoint to fire in the current TMC profile code. How big is this - or perhaps a no issue?

I've set up a separate project to test out how I can let the scpi parser handle this.

This is software only, running the "firmware" on my laptop. No Pico involved.
Also the reason that I'm using Eclipse in this case. It's set up for on-PC dev and debug.

[mention:ef601b47037147bfb9b0b4a3ab63026a:e9ed411860ed4f2ba0265705b8793d05] , you have experience with status registers (https://goughlui.com/2021/05/15/tutorial-understanding-the-scpi-status-model-with-pyvisa-examples/)

If I want to enable a user to listen to a digital pin change status, and if I want to flag that change in the status register(s),
what would you expect to see?

What would be the way for the user to request this?
What would be the way for the instrument to flag this?

The instrument supports 3 input pins, and I'm experimenting to implement notification of their status change, if requested.

[mention:acaf6a9338de4eef8f6717d5561ed01d:e9ed411860ed4f2ba0265705b8793d05] could you re-link the NI article: “NI's Using Instrument Status Registers and Service Requests in LabVIEW” - seems to be broken.

This is pure awesome! It was on my bucket list, very encouraging, you did great strides [emoticon:1435ff2429184e17bc948e4f19178e1e][emoticon:1435ff2429184e17bc948e4f19178e1e][emoticon:1435ff2429184e17bc948e4f19178e1e]
