SPI1 missing on the Rapsberry Pi Pico pinot diagram on pin 26 to 28

[Keuronde]

On the pinout diagram, the pin 26, 27 and 28 do not indicate that they can be used by the SPI1.
See https://www.raspberrypi.com/documentation/microcontrollers/pico-series.html

The SPI isn't a full SPI port so to keep things simple it isn't in the diagram. The datasheet contains all the options available for each pin.

What @dp111 says is correct, and is also the reason that the UART functions aren't shown on those pins in that simplified pinout diagram.
