Looking at the diagram of connector on the new XRP controller, it seems that pins GPIO16-GPIO19 are available for user. Do I understand correctly that it means we can use them for connecting SPI devices? (according to RP2350 datasheet, these pins can be used for SPI0)?

Yep! In fact, GPIO 12-19 are all completely free for the user with almost all features available, including SPI. So you can use both SPI0 (GPIO 16-19) and SPI1 (GPIO 12-15) for whatever you want!

Wow, that’s great news!
First thing I’ll try is adding a small SPI TFT display…

Indeed, the SPI display works.
I’ll post proper documentation once I clean it up a little
