Hello, I'm still new to the Atmega4808 processor. So far it has been great and I have figure out a lot about the pinout. But Now I would like to use the Spi on the processor and Stumped because it looks like it has two Spi channels. Which one should I use as the primary Spi? I have attached a image below. I have figure the I2c pins as Pa2 and Pa3 But so far not the Spi pins. Can someone please help me to figure out what spi pins should I use?
