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.
