Remark :

1. Capacitor between C2N and C2P can be omitted only if doubler is enable.

2. Resistor across OSC1 and OSC2 can be omitted if external oscillator is used.

3. VR and VF can be left open for Regulator disable, TC = 0% and Contrast Disable.

4. RES, CS, R/W and D/C should be at a known state.

5. CS line low at Standby Mode.
