The Port type exposes the following members.

Constructors

	Name	Description
	Port(Cpu. . :: . .Pin, Boolean)	Initializes a new instance of the Port class with the specified port identifier and initial state.
	Port(Cpu. . :: . .Pin, Boolean, Port. . :: . .ResistorMode, Port. . :: . .InterruptMode)	Initializes a new instance of the Port class with the specified port identifier, glitch filter state, resistor mode, and interrupt mode.
	Port(Cpu. . :: . .Pin, Boolean, Boolean, Port. . :: . .ResistorMode)	Initializes a new instance of the Port class with the specified port identifier, initial state, glitch filter state, and resistor mode.

Methods

	Name	Description
	DisableInterrupt	Disables the interrupt for this NativeEventDispatcher object. (Inherited from NativeEventDispatcher.)
	Dispose() () () ()	Releases resources used by this NativeEventDispatcher object. (Inherited from NativeEventDispatcher.)
	Dispose(Boolean)	Disables the pin for a port and marks it as available for reuse. (Overrides NativeEventDispatcher. . :: . .Dispose(Boolean).)
	EnableInterrupt	Enables the interrupt for this NativeEventDispatcher object. (Inherited from NativeEventDispatcher.)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Performs cleanup operations. (Inherited from NativeEventDispatcher.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Read	Reads a Boolean value at the port input.
	ReservePin	Reserves or releases a specified port pin.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Events

	Name	Description
	OnInterrupt	Adds or removes callback methods for native events. (Inherited from NativeEventDispatcher.)

Fields

	Name	Description
	m_callbacks	The event handler for this NativeEventDispatcher object (a mulitcast combinable delegate). (Inherited from NativeEventDispatcher.)
	m_disposed	Set to true if this NativeEventDispatcher object has been disposed, or false if not. (Inherited from NativeEventDispatcher.)
	m_threadSpawn	The event handler for this NativeEventDispatcher object (a mulitcast combinable delegate). (Inherited from NativeEventDispatcher.)
