・It is required to have the inverter designed so that to allow the impedance deviation of the four CCFT
Otherwise, when one side of the CCFT is open, the excess current may possibly be applied to the other
side of the lamp.

Regarding the vertical display position, the data starting form following ENAB rising is displayed
at the top of the active area in case of no rising ENAB more than 2003clk from ENAB rising.
