5.3.2 External
In order to use this function, a user must connect the soldering pad “JP1”. When the soldering pad
“JP1” is open-circuited, this function is not valid and when it is short-circuited, the third hole (pin #3)
is used for external reset input. If low level signal
longer than 500ns is input into the hole, reset
function being same as power on reset is executed.
5.4 Soldering Land Function
Some soldering lands are prepared on the rear side of PCB, to
set operating mode of the display
module. A soldering iron is required to short soldering lands.
