Non-locking function keys can be used and there is no need to prevent bounce. ‘The input pins contain pull-up resistors to achieve a high noise margin even under open conditions, The outputs have a resistive load, and both wired-AND connection and transistor drive are possible. When the power is switched on, the automatic reset function is energized and the mode is set to STOP.
