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 returns to its previous state or if it is reset.
