Please note that LCD driver must be turned off before the entering sleep mode. That means user must
clear the bit 0 of LCDC to turn off LCD driving circuit before setting bit6 of OP1 to enter sleep mode.
Large current might happen if the procedure is not followed.
Please also note that LCD driver uses slow clock as clock source. The LCD display will not display
normally if it works in Fast clock only mode because the LCD refresh action is too fast.
There are two LCD driver configurations.
