Multiple Key Presses
Although the LC75853NE/NW is capable of key scanning without inserting diodes for dual key presses, triple key
presses on the KI1 to KI5 input pin lines, or multiple key presses on the KS1 to KS6 output pin lines, multiple presses
other than these cases may result in keys that were not pressed recognized as having been pressed. Therefore, a diode
must be inserted in series with each key. Applications that do not recognize multiple key presses of three or more keys
should check the key data for three or more 1 bits and ignore such data.
