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 to the
state it had before or if it will be reset. In RSMEMORY, the RESET input has priority over SET input.
