When the display module includes the serial data input option, Pin 3 is internally connected to provide
signal E2 as an output to a second display module.
CMOS Note: Care must be taken to insure that input signals do not exceed the supply voltage or ground
levels. Data cables must be as short as possible to reduce signal overshoots.
