Hello!
I'm designing a board with ESP32-C3FN4 and I need to use its SPI interface to talk with another board. The ideia is to use SPI2 (full-duplex) in slave mode, but I'm kind of lost which pin I can use. On "Peripheral Pin Configurations" block of datasheet, it says "Any GPIO pins" can be used, but on "IO MUX Pin Functions" table, the "FSPI" pins are function 2 of determined pins. So the question is, can I use - for example - FSPICLK on GPIO1?
Thanks a lot!
