The custom LCD glass module used on MB979 daughterboard is XHO5002B. To optimize
the number of driving signals, the display elements are connected to eight common planes
called COMx (LCDCOMx in the schematic digrams), where "x" can be substituted with
figures from "0" to "7". The other pole of each display element is called segment, SEGy
(LCDSEGy in the schematic diagrams), where "y" can be substituted with figures from "0" to
"39". Each combination of COMx and SEGy addresses one display element.
