Clear function will clear the display. The Flash RAM will be set to all zeros. An ASCII blank code (20H) will be written into the display
memory. The user must wait 3.0 ms or write a new control word to the display with control word bit D7 = 0 to disable clear before writing
any data to the display memory, otherwise all new data to the display memory will remain cleared. See Switching Specifications for clear
function timing.
