Flash RAM Function
Character Flash is controlled by FL pin, bit D0 and control word bit D3. Combination of FL being low, proper digit address and D0 being
high will write a flash bit into the Flash RAM Register. In the control word mode when D3 is brought high, the above mentioned character
will flash.
