Enum itsybitsy_m4::UndocIoSet2

pub enum UndocIoSet2 {}
Expand description

Type-level variant of IoSet representing an undocumented SERCOM IOSET

After implementing IoSet type checking, it became clear that some existing boards were using a combinations of pins that did not match any IOSET in the datasheet. From that, we infer that there must be at least two undocumented IOSETs, and we added these new IoSets to account for it.

As of writing this documentation, only two undocumented IOSETs have been discovered:

  • UndocIoSet1: PA16, PA17, PB22 & PB23 configured for Sercom1. Both the pygamer & feather_m4 uses this combination.
  • UndocIoSet2: PA00, PA01, PB22 & PB23 configured for Sercom1. The itsybitsy_m4 uses this combination.

See the type-level enum documentation for more details on type-level variants.
