Clear Function
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 3 µs 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.
