pro_alonegpio documentation [solved]

[cnlohr]

I was wondering if espressif had any comment regarding the use of the functionality "pro_alonegpio_in0" or "pro_alonegpio_out0" within the mux block. Or if it was never fleshed out. I don't see anything in the datasheets or on google.

Also, I'm super curious about sig_in_func_223 :-p

What chip is this for?

Honestly any :-p But right now, between work and MAGFest (we're making another 2k swadges) It's all on the ESP32S2, so I figured I'd spin up and see if I could get any YT vids out of it.

PRO_ALONEGPIO_*_IDX are the signals for the dedicated (fast) GPIO functionality. The registers to configure this are in the TRM, DEDIC_GPIO_*and there's a high-level description of how it works in section 5.4. There's alsi a high-level driver for it in esp-idf.
What makes you so curious about signal 223? Is it used somewhere?

Thank you for the keywords. Searching the datasheet for "alone" left me coming up clueless. I am eager to give this a shot. Thank you.

Re: 223. It was just something I noticed on the mux map.
