Function
Normal display.
LCD display blanked. The COM signals of LCD driver output inactive levels
(LVL4 and LVL1) while SEG signals output normal display patterns.
LCD driver disabled, LCD driver has no output signal and applied to VDD
LCD driver Enabled.

Please note that LCD driver must be turned off before the system goes into "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 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.

Oscillators
The MCU is equipped with two clock sources with a variety of selections on the types of oscillators to
choose from. The system designer can select oscillator types based on the cost target, timing accuracy
requirements etc. Crystal, Resonator or the RC oscillator can be used as fast clock source, components
should be placed as close to the pins as possible. The type of oscillator used is selected by mask option
MO_FXTAL.

RC Osc.
The RC oscillator has a built-in capacitor. An external resistor is needed to connect from FXI to GND to
determine the oscillation frequency. The capacitance of internal RC oscillator is selected by mask option
MO_RCAP[2..0].
