Detailed Description

Flip flop implementation for a RS flip flop with dominant RESET.

RS (reset-set) flip flops act as a fundamental latch. It has two input lines, S (set) and R (reset). Activating the set input sets the output while activating the reset input resets the output. If both inputs are activated, the output is deactivated, too. This is why the RESET line is called dominant. Use a SRFlipFlopImplementation for a dominant SET line.

Member Function Documentation

getState()

bool RSFlipFlopImplementation::getState ( double dt, DigitalComponent::InputMap input, bool & q )

virtual

evaluates the output state from the input lines

Parameters

dt	the elapsed time in seconds from since the last call
input	a map of named input lines
q	a reference to a boolean variable to receive the output state

Returns

true if the state has changed, false otherwise
