14.3.10 Reset-set with memory function block RSMEMORY
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
the flip-flop after a power interruption will return the state it had before or if it will be
reset. For a Reset-Set flip-flop, RESET input has higher priority over SET input.
