·Writing to display data

If VDD and VEE voltages are not same, connect the

logic system power supply (VDD) first.

If VDD and VEE voltages are not same, disconnect

the booster circuit power supply (VEE) first. After

VEE, VOUT, V0, V1, V2, V3 and V4 voltages are

below LCD ON voltage (threshold voltage for liquid

crystal turns on), disconnect the logic system power

supply (VDD).
