Set-reset with memory function block SRMEMORY

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 the flip-flop after a power interruption will return the state it had
before or if it will be reset.
