Hi, Voggeneder

    You need one more general purpose I/O pin to control /DISP_OFF signal. You may find the step by step detail in the user's manual of MC68EZ328.
    Generally, VEE is the power supply for LCD panel. Normally, it should be about 20-30 volts. The polarity can be either positive or negative, see the user's manual of the LCD for the detail.
    VLCD and FG are also quite strange for me, sorry.
