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, after a power interruption, the flip-flop
resets or returns to the state it had before the power interruption. For a Reset-Set flip-flop, RESET
input has higher priority over SET input.
