The Set-reset with memory function block (SRMEMORY) is a flip-flop with
memory that can set or reset an output from two inputs respectively. Each
SRMEMORY 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. The input SET has priority.
