Functionality
The Set-Reset function 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. For a Set-
Reset flip-flop, SET input has higher priority over RESET input.
