5.171 L_TbFlipFlopD - D flipflop
This FB is created as a D flipflop and can be used to evaluate and save digital signal edges.
• With each rising edge at the clock input bClk the current status of the input bD is saved internal-
ly and output to the output bOut.
• The flipflop can be reset by a TRUE signal at the reset input bR which has the highest priority.
