Functionality
The Reset-set function (RSMEMORYQT) is a flip-flop with memory that can reset or set
an output from two inputs respectively. Each RSMEMORYQT function block has two
outputs, where one is inverted. The memory setting controls if the flip-flop after a power
interruption will return the state it had before or if it will be reset.
