pub trait IoSet: Sealed {
type Order;
}Expand description
Type-level enum representing a SERCOM IOSET
The SAM D5x/E5x has particular sets of Pins that are allowed to be
used together for each Sercom, and Pins from different sets cannot
be used together. The valid combinations of Pins are called IOSETs
(or IO SETs) in the datasheet. Additionally, some undocumented sets are
used in commercially available boards (such as Adafruit’s PyGamer and
Feather M4). This IoSet trait is used to constrain the various Pads
types (spi::Pads, uart::Pads, and i2c::Pads) to only contain
valid documented or undocumented sets of Pins.
See the type-level enum documentation for more details on the pattern. Typenum unsigned integers are used to make IoSets comparable
