Display contrast adjustment circuit state
The display contrast adjustment circuit is disabled, and the VLCD0 pin level is forced to the VLCD level.
The display contrast adjustment circuit operates, and the display contrast is adjusted.
Note that although the display contrast can be adjusted by operating the built-in display contrast adjustment circuit, it is
also possible to be adjusted by varying the voltage level on the LCD driver block power supply VLCD pin. However, the
level on VLCD0 must be greater than or equal to 4.5V.
