Functional Description:
The Pulse Width Digital Input generic hardware operator provides access to a digital input channel resource in the physical hardware capable of measuring digital pulse widths. When the generic operator is linked to a specific hardware resource, its output value will correspond to the time duration of a digital pulse (from rising edge to falling edge).
Operator output represents the pulse width, expressed in seconds or milliseconds (the output format is a property of the operator). Output indicates when a new pulse width measurement becomes available. The output is HIGH for one schema compute cycle each time a new pulse is measured; otherwise the output is LOW. Output remains unchanged between pulse readings.
The operator has a reset input x which clears its outputs (sets and ).

User-Defined Properties:
Object Name. A string label that identifies the operator.

Display Reset Input. This property determines if reset input pin x is visible in the schema diagram. Design Pad issues a warning upon processing the schema when the pin is visible but not connected. The warning message is not issued when the pin is not visible (when this property is not checked).

Output Format. Determines the time unit of measure (seconds or milliseconds) that the pulse duration should be expressed in.

Comments: None.
