; This is meant to be used with a 40x4 character display (containing a dual hd44780-compatible controller) like the TM404A.
; This kind of display uses two controllers to overcome the hd44780 controllers limitation of 80 addressable characters.
; It is seen as two separate displays, and thus have two EN pins. A finer implementation would apply some deconding logic to
; an address bit to use a single port, but here we will use two different IO ports to save an IC.
