The function block Set-Reset (SM) (figure 22) with/without memory has two inputs,
designated SMnn-SET and SMnn-RESET, where nn presents the serial number of the
block. Each SM circuit has two outputs, SMnn-OUT and SMnn-NOUT (inverted). The
output (OUT) is set to 1 if the input (SET) is set to 1 and if the input (RESET) is 0. If
the reset input is set to 1, the output is unconditionally reset to 0. The memory setting
controls if the flip-flop after a power interruption will return to the state it had before or
if it will be reset.
