Keyscanning and display timing
The value is fixed by the internal clock from the oscillator.
One cycle of keyscanning consists of one frame, and data of 8x2 matrices are stored in the
RAM.
Note that the keyscan is only at the end of the frame when the display is ON. When the
display is OFF, the keyscan takes place continuously. The grid/digit is turned off during the
keyscan.
