The function code is used to set the polarity of the
output terminal.
When the current bit is set to 0, input terminal is
positive.
When the current bit is set to 1, input terminal is
negative.
The function code defines the corresponding delay
time of the electrical level change during the
programmable terminal switching on and off.
