Functionality
The Reset-set with memory function block (RSMEMORY) is a flip-flop with memory that can reset
or set an output from two inputs respectively. Each RSMEMORY 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. For a Reset-Set flip-flop, RESET input has higher
priority over SET input.
