I've been bungling through my first project with my new Itsy Bitsy M4, trying to make SPI work, and discovered the IOSET issue well documented in other threads. With that in mind, the pins labeled for SPI on the board's schematic don't make sense to me anymore:
SERCOM1: SPI
PA00: MOSI
PA01: SCK
PB23: MISO
Except according to the chip datasheet (DS60001507F Rev. F - 05/2020), PA00 and PA01 are from IOSET 4, while PB23 is from IOSET 3. What am I missing here?
