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.
