System Reset input pin. Level trigger, active low on this pin will put the chip in reset
state.
External fast clock pin. Two types of oscillator can be selected by MO_FXTAL (‘0’
78, O, for RC type and ‘1’ for crystal type). For RC type oscillator, one resistor needs to be
79 B connected between FXI and GND. For crystal oscillator, one crystal needs to be
placed between FXI and FXO. Please refer to application circuit for details.

7. LCD Power Supply
The built-in LCD power supply is equipped with input voltage regulator, voltage charge pump and bias
voltage generating circuit with active buffer instead of passive resistor voltage dividing network. The
input voltage is regulated to LVL2 using the internally generated reference voltage. LVL2 can be adjusted
by resistor between LCDGS and LVL2.
LVL2 adjustment guideline: First, the level of VDD must be 0.3 volt higher than LVL2 even at the end of
battery life for the regulator to function properly. For example, if the VDD is expected to drop to 2.2 volts
