The board is compatible with Arduino UNO and Arduino MEGA shields and has an ISP connector, so this adds the corresponding features. This adds the Arduino I/O-mapping for the ISP SPI and provides the corresponding feature. It appears that the SPI on D11/D12/D13 cannot be provided by a SERCOM, this is under clarification at [1]. For now, no I/O mapping for that SPI bus is provided. [1]: https://forums.adafruit.com/viewtopic.php?t=214093
