Port

Informative

The Port driver (PortDrv) — a thin, portable abstraction over the MCU’s general-purpose I/O: it reads and writes pin and port values, toggles pins, and detects pin edges. Pin functions and directions are established at initialization from the configuration. The driver builds on the shared foundation in General.
